Today, even Russian hunters of the old formation are spoiled by a large variety of semi-automatic, even the most of them had a desired dream - the Tula self-loading rifle of MC 21-12. Today, this single person, despite the fact that it continues to be produced by a tonic, is considered bad and outdated in all respects. Especially for young hunters, for which the hunt is only a tribute to fashion or the type of business corporate. In such circles, a gun is not a tool, but the indicator of the social status of its owner. In this article, we will not praise the well-deserved veteran of the Soviet Armory. And I will not hide it with mud, lifting all the flaws. The purpose of the article is to look at the hunting weapon of MC 21-12 from the position of modern fisherman, which fully managed to taste the diversity of both imported and domestic "self-charging".
History of weapons
Probably, the MC 21-12 guns for his more than a fifty-year-old history did not write only lazy, so we in this article simply recall the most important events in the life of this weapon and also briefly focus on its technical characteristics and design features. This "self-charging" is truly a cult for many of the fisheries of the past, so even this information that has been used by the OKOMIN may be useful to someone, well, or will be at least theoretically interesting. So, the rifle of MC 21-12 (the photo is given above) was created by the designer Nikolaev V.A. It is a self-loading single-tier weapon for commercial and amateur hunting. Initially, in the period from 1956 to 1964, this model was manufactured in CCIB SOO. In addition, until 1965, MC 21 was also produced on the 16th, and 20th calibers. At the Leipzig Fair, held in 1965, this model was awarded a gold medal. In the same year, the release of the gun was transferred to the tension. Until today, MC 21-12 was produced only in the twelfth caliber.
Description of nodes and mechanisms
The automation of weapons is based on the principle of rollback at the return of the spring-loaded rolling trunk and the gate mechanism, which is longitudinally sliding according to the browning system of the 1905 sample. Recharge is carried out as a result of using a rather long stroke of the trunk at the time of its movement in the rear, and then in the front position. The removable barrel of 750 mm long has a vents of the ventilated type. Patronics - 70 mm. Details of the USM, the dool channel and the shutter are chromed, it greatly facilitates the care of weapons, and also increases its durability.
Block locking is carried out by a longitudinal-sliding gate. His fighting emphasis is fixed for the opening of the shank. At the progenitor of this model, AUTU-5 production of Browning, this emphasis has a rectangular shape. So, in one of the numbers of the magazine "Hunting and Hunting. The economy "Karkov V. (Honorary Member of Moor), describing the delay characteristic of the MC rifle 21-12 - the non-disconnecting of the shutter and the trunk during a shot, focused on the round form of the stop as the cause of this defect. Of course, the truth in the words of the old hunter there is, however, it should be understood that the change in the form of combat stops, so to speak, simplifying the design, is explained by the need to circumvent the construct of Browning. In addition, the time of release of the gun should be taken into account, in the fifties, no one would allow the production of a flawed model. The causes of problems with weapons, subject to the exception of constructive flaws, usually lie as assembly and manufacture. Also should not forget about the quality of ammunition.
The hunting gun of the MC 21-12 has a wrap-type USA, assembled on a separate basis. The extraction of the sleeves is carried out at the time of the trunk in the front position. With the screen, the shot is impossible.
Short description
(The photo given in this article will help the reader to draw up their opinion about this weapon) has a tube tubular store with a container for four cartridges. The housing serves as a guide for the movement of the trunk. Cartridges from the climax are fed by a shutter when it moves to the front position. The store filling is carried out by one ammunition, through the window at the bottom of the receiver. If the shooter is necessary, the arrows can block the flow of cartridges from the rope, turning on the cutter mounted on the left side of the box. The non-automatic flag type fuse provides a locking of the trigger. A curious feature is the ability to permutate the flag on the left side. Butt MC 21-12 pistol form. The box is removable, it is fixed by spring-loaded nut on the store housing.
Tactical and technical characteristics
Weapon weight is 3.2-3.4 kg. -1285x65x200. The effort of descent is 1.5-2.5 kg. Sometimes no more than 3.7 kg indicate in the literature. If you compare with modern self-loading guns based on aluminum alloys, it is quite a lot. However, MC 21-12 is completely made of high-quality Tula steel, it has a large margin of safety. The manufacturer guarantees 6500 shots. If the reader doubts, there is a lot or a little, then the Izhevskaya "Saiga" can be brought as an example, the warranty for only 2000 shots.
However, back to our gun. The reserve of safety of this weapon is so large that with proper care it can serve for a very long time. Breakdowns even after ten thousand shots are very rare. This is such a reliable model - MC 21-12. The characteristics of this rifle speak for themselves. Try to produce 10,000 shots from imported "self-charging" of the basic configuration, it is hardly possible for you. Owners of this rifle should consider one feature - only ammunition with plastic sleeves can be used. The manufacturer categorically prohibits the use of metal and paper cartridges.
Every millet will not be
Consider another unique side of the MC model 21-12. Reviews and relaxation of opinions about it are probably inferior in the sharpness of the discussions of opponents and supporters of Saiga. In essence, it applies to any rifle. After all, we are all different. Paul, age, type of higher nervous activity, social status and level of income, experience in handling weapons and hunting, presence or lack of desire / ability to do something with their own hands, etc. All listed factors will inevitably affect the perception of phenomena and objects making them special for every personality. Well, and if we take into account the bright individuality of any weapon model, which is not made on streaming lines of CNC machines, then it becomes clear: it is impossible to wait for a single opinion from such a variety of hunting community about a very ambiguous MC 21-12 rifle.
Tips for experienced hunters will help to deal with the main problems of this weapon. They are known to many, and all of them are heal in a home workshop. Simply put, any hunter, whose "from the right place" grows hands, having a couple of free evenings and a minimum set of tools, can make its semi-automatic with absolutely reliable and trouble-free in use.
What to do: buy a foreign car or support the domestic producer?
Those who do not want to think and watch, it is easier to acquire imported "self-charging." Such one-rod beautiful, easy and almost trouble free. For one small disadvantage: the price of such a weapon can be at times, and then an order of value above the value of our MC 21. There are also the so-called budget models, but their quality cannot be compared even with our "handicraft" production, this is money thrown into the wind .
Today, the whole world is once the economic crisis, the value of imports is growing steadily, as a result of which their deliveries are reduced. Domestic gunsmiths have an excellent chance to take the niche of this market not only in Russia and the CIS countries, but also in Europe. Agree to buy inexpensive inventory of Russian gunsmiths inexpensive inventory and, if necessary, refine it to be slightly, than to stay at all without your passion. Turkish lots of problems do not solve their self-loading single-tie guns and more expensive domestic, and with quality similar problems, although commercials are reversed.
The MC 21 was valued by experienced hunters in the past time, and now it is bought by those who cannot afford expensive weapons or experienced connoisseurs. Of course, this rifle has modern competitors, such as the legendary "Murka" MR-153, Tzoz-87 and "Bekas-Auto". "Bekas" and "Murka" are also very ambiguous representatives of hunting semi-automatic matters, but Tzoz-87, whether it is made at a better level, could be the best domestic self-loading rifle. The title of "People's" on our right occupies MR-153, but its cost is one and a half times higher than the MC 21-12, and compared to it, this model is often inferior as the production of the trunk, has a narrow uncomfortable targeted bar, and also characterized by the infancy of the dangu Nozzles The guns of Tula gunsmiths are traditionally distinguished by excellent trunks and wonderful fights. Many hunters purchasing MC 21 today make their choice precisely thanks to these qualities.
Debugging and finishing according to the method of automation system
In one of the rooms of the magazine "Hunting and Hunting. The economy "was published an article Azarov A., in which he gives recommendations on debugging a rifle of MC 21-12. Below we will look at what the author advises.
A huge role in the work of automation playing a tight system. Sometimes the rifles come to sell, the trunks of which are not chamfering in the brake clamp ring. In such copies, a pair of buffer rings is placed at the store. The author of the article recommends the owners to make small chamfer on the rings on their own, otherwise the mechanisms will start scratching with sharp edges of each other, while in the literal sense the chips will be filmed. In addition, the burdens on the clip will interfere with the functioning of the sliding system.
The trunk locking process also has a decisive role in the performance of automation. The combat stop of the shutter, being in the front position, rises up and enters the shank window of the trunk. Its cylindrical part of it can noinaclely fit to the walls of the window. It is necessary to watch with a collected rifle with a lid-lid box, a dense fit should be only in the rear. If it is not, then when shooting focus it will make a slope on the cutting of the shank. On some copies, such a gap can reach one millimeter is unacceptable. Now in armory stores can be purchased for the MC model 21-12 parts, so to speak, for all occasions. So, combat stops are produced with the diameters of the cylindrical part of 10.7 to 11.9 mm. It is necessary by the selection to eliminate this drawback. Strong tension and bad polishing in this part are also unacceptable, as the degradation of the shutter and the trunk will occur.
Possible malfunctions, debugging and adjustment of the gate mechanism
From above on the end of the shutter on the left there is a retainer, and on the right - the ejector. It is necessary to visually and to touch the quality of grinding, if there are burrs, carefully remove them with velvet skurt. If the liner on the shutter is plastic, it is better to replace it with a metal, in order to avoid chilling. In addition, it is necessary to check the density of the stroke of the mechanisms. Large transverse shutter shutter is not allowed in the packs of the box. If it should be sided from side to side, it should not be praised, otherwise it can lead to the breakdown of mechanisms. In addition, check the feed tray. It should be on a par with a store window (displacement is unacceptable), there should be no burrs on it, as the cartridges will slow down at the time of slip on the tray. All mechanisms must be polished, otherwise the ammunition will be cling to irregularities. Cartridges for MC 21-12 also should not have defects on the external surfaces of the sleeve.
In the assembled state, the lower right ledge of the shutter should squeeze the right stop in order to avoid delays in the exit of ammunition from the closure to the limiter. Sometimes in poorly debugged weapon, he skips. In this case, the right stop is not recessed in the groove on the box. This leads to a jams of the cartridge in the clip. It can occur after intensive exploitation of a gun when the barrel and the end of the shock absorber of the Tsevaya is broken. As a result, the shutter will begin to go farther further. In this case, the repair is reduced to feed and fix the shock absorber of the Tsevaya. Under it can be glued specially sharpened ring.
In the event that the shutter is a bit left back, the right stop must fix the ammunition in the clip, resting in the flange of his sleeve. If this does not occur (dirt in the sinus or broken spring), then the cartridge falls on the ground. This happens when the shutter, moving forward, will eliminate the next ammunition with a raised tray into the cartridge, and the next it falls under it. It can also occur with the diameter of the liner flange. If the feed latch is delayed in the groove at the time of refining back, the tray rises upwards, and the trunk, moving forward, dries off the left stop and release the cartridge, which falls to the ground.
Debugging and finishing the trunks
As a result of the fact that the cover of the lid protrudes over the box, the Tsevier guns sits closely on the place put it, the clamps may not fit into the ends of the grooves. As a result, the bed is spinning on the clip. In this case, it is necessary to adjust the box cover. Sometimes there are copies that have an end rope can be fastened to zevyu with distortion, as a result, the trunk will be inhibited when the inner wall rolls back. In this case, it is necessary to clean the wooden surface in these places. If it does not help, then it is necessary to set the clip again.
It is also necessary to draw attention to how the combat spring is installed in the USM. Does she prevent her right wall in his work? In the assembled position, remove the cover and check whether the trigger pushers are pressed. It should be verified whether the support (front) washer is shifted by the hole on the hole, otherwise it can damage the thread at the end of the clip and will weaken its fastening.
General debugging
There are instances that have a great shine flange after a shot. This happens as a result of a bad fit of the locking mechanism. Detect this defect is possible only after shooting.
Before exploiting a gun, it is necessary to determine the temperature of the brake spring to the diameter. With this ring to wear it on the store tube. You should also smooth the sharp parts on the last twist of the springs. In this case, the cutting tube will not scratch.
Drying the shutter, it is necessary to trace so that the rod and springs in the shank box do not occur. If anything bothers them, the reason should be eliminated. In addition, you need to check the operation of the ammunition cutter. If you turn the checkbox counterclockwise, the cartridge should stop on the cut-off when pulling the shutter. And in the future, do not reach the left stop.
Rifle MC 21-12: Price
Due to the fact that this weapon is already removed from production, it is difficult to find on the shelves of weapons stores. However, it is not necessary to despair, there are still there, and if desired, they can be ordered, however, it will have to wait some time. The disadvantage of such a purchase will be the fact that you will not have the ability to choose the best among several copies. So it is still better to find a store that has this weapon still in stock. So, you decided to buy a rifle of MC 21-12. The price of such a "self-charging" will be approximately 15 thousand rubles, but if desired, we can also purchase weapons on the secondary market. In this case, it will be much lower it.
Summary
Many young hunters scares the principle of automation in this rifle - the trunk rollback. However, one should not forget that this scheme was the only operating up to the end of the 80s of the last century. The first serial semi-automatic guns with a gas-conductive system appeared only in 1990. A little more than twenty years have passed - and on the shelves of weapons stores you can see the slender ranks of the gas-sized "self-charging", and the system with a rollback of the trunk is represented only by the MC model 21-12. Feedback Hunters Polaria about this gun is unequivocal. It turns out that in these difficult weather conditions there has never been and there is still no alternative to this weapon. Defined MC 21-12 at autumn temperatures up to twenty degrees of frost showed itself accurate and reliable assistant. Until now, it is used in the north both for the extraction of deer, and if it makes a very sharp and teaching battle that allows you to beat the bird at distances to seventy meters.
Today, the rifle MC 21-12 is still in demand by hunters. Often, a new copy is running unfortunately, refuting evil sprinkles, right "out of the box." True, the inverse situations happen when the gun does not want to work at all. However, in this case, it is enough to spend a hour - two times, armed with a supfil so that it makes it like a clock. Given the attractive price, the gun acquire both experienced hunters and newcomers. Soviet assembly specimens are especially valued. Despite its solid age, they still have their own owners.
So write off the MC 21-12 gun, despite its disadvantages, from the arsenal of domestic hunters until we hurry ...
Probably, every our compatriot who is fond of hunting, heard about the semi-automatic rifle of MC 21-12. It is one of the most common from among those developed and issued in our country. Weapons have a number of important advantages that should be known. But it also has certain disadvantages, knowing who the hunter can decide: to give preference to this semi-automatic or to search another option.
History of weapons
Let's start with the fact that it is MC2112 that became the first Soviet semi-automatic smooth-bore gun. Although the designers also tried to create it as original as possible, but as a result of the long work, they concluded that it had features inherent in foreign counterparts. Which, however, is not surprising - the years ended almost to perfection, it simply could not do not go on the paths already designed earlier. For example, the automation scheme turned out to be similar to the browning, and the easiest pickup cover of the receiver strongly resembled the Italian semi-automatic semi-automobiles from Breda Antares.
MC 21-12 was created on the Tula weapon factory under the leadership of V. A. Nikolaev in 1956-1958. Several test specimens were released, but they revealed certain disadvantages. Then it was decided to transferring the launch of serial production until they were completely eliminated. Therefore, the first samples came from the conveyor only in 1965.
First, the weapon that received the nickname among the hunters "Soviet browning", received predominantly negative reviews - the reason was bad compatibility with the folder sleeves, which were widely distributed at that time. But gradually, as the appearance and distribution of plastic analogues appears, more and more supporters appear at guns.
However, it was estimated not only in our country. So, in 1965, the gun received a high award - a gold medal at the Leipzig Fair, which is a serious recognition of quality.
As a result, both in the Soviet times and later, already in the Russian Federation, more than 300 thousand guns were released - a very good indicator.
Specifications
Now briefly tell about the technical characteristics of MC 21-12. A rifle, having a barrel length of 750 millimeters, provides a magnificent range of combat - both fractional and cartridges and bullets. The total length is 1285 millimeters - a rather serious indicator, due to which people are below average growth, as well as adolescents to handle it is not too convenient. This should be required when buying weapons.
Weight is a 3.4 kilogram - not too much, thanks to which a man who is familiar to long-term transitions can use it both with a stand archery and with a corruption hunt. Most of the analogues - semi-automatic 12 caliber - weigh from about the same, with a difference of 100-200 grams in one direction or another.
Designed for firing cartridges 12/70. It has a dual narrowing of 1.0 - a complete chock, which additionally provides a high combality of the fight by fraction and a creek at a large distance.
When charging, the first cartridge is immediately sent to the chamber. Four more are inserted into the contractor. Thus, without additional charge, the hunter can take five shots in a very fast pace, which allows you to shoot a shooting, for example, on a flock of ducks or geese, and quickly pursuer podrangekov.
Existing modifications
In just over the years of release, several weapons options were developed. Between themselves, they are not too different - the characteristics of the MC 2112 rifle remain the same. But still, it will be useful for them to know every felt shooting that decided to acquire this particular semi-automatic.
So, the name of the MC 21 received the very first model, several options of which were released to the official start of manufacture - from 1956 to 1964. Then they created guns under the caliber 12, 16 and 20 to check which it would be most successful.
A well-known hunters model MC 21-12 became the second and went to serial release in 1965.
Subsequently, it was slightly modified. The population of the butt was supplemented with a rubber shock absorber, thanks to which MC appeared 21-12.
But the last model was improved. This modification received not only the rubber shock absorber, but also replacement dangle nozzles, allowing you to choose the model suitable depending on the purposes of the arrow and the model's existing ammunition. She got the name MC 21-12MR
Although today the MC gun 21-12, the characteristics of which are painted above, has already been removed from production, some amount was released after the collapse of the USSR. Unfortunately, it is they, quite often in the hands of young hunters, create an illusion of the extremely low quality of weapons in this series.
Yes, unfortunately, a rifle who received excellent reviews from experienced Soviet hunters was practically destroyed due to poor-quality manufacture. First of all, the quality of the assembly suffered - because of this, the number of slots of the sleeves during the emission increased. In addition, in order to increase the speed of assembling weapons, pre-chromed nodes began to be used. As a result, the debuggers had to finish the details right by chrome. The quality of heat treatment of components has decreased. Many owners began to complain about the poor quality of wood processing and sowing on metal. Of course, seeing such a weapon near, the hunter immediately loses the desire to purchase it.
However, if you manage to purchase a semi-automatic, manufactured in Soviet times and preserved in good quality, we can assume that you are lucky - I don't have to regret such a purchase. Even with minimal care and active operation, it is guaranteed not to serve not one decade.
Benefits
One of the main advantages is a significant shooting range - this is ensured by a long barrel, as well as the muzzle narrowing.
An additional advantage can be called a lightweight juro - you can make a shot particularly gently, smoothly. So, the shooter will not face too strong return.
It is also worth highlighting a superbly worked design MC 2112 - photos clearly demonstrate it. Hold him in his hands and shoot - solid pleasure. It is no coincidence that so many years have been spent on final refinement.
The maximum simplicity of the mechanism device provides high reliability and considerable service life.
Chroming protects the metal from rust, allowing you to use even in harsh conditions - in the rain, with high humidity.
Finally, the rifle has a relatively low cost, which is also a very important parameter for many potential buyers.
disadvantages
But perhaps there are no weapons devoid of flaws. Not exception and MC 21-12.
Start with the fact that it is impossible to shoot from a gun with calibered bullets - a complete choc will lead to the fact that the trunk will sweep. Only subcalacer analogs are suitable. However, most of the cartridges sold in stores are charged with them.
A hole in the butt where the return spring is placed, it may become a place of moisture condensation - for example, when in fog or other conditions of high humidity. Therefore, after each such "wet" hunt, the butter is desirable to carefully dry.
Well, and, as noted above, modern rifles simply cannot boast high-quality processing and assembly.
Purpose
Initially, weapons were used exclusively for hunting. However, today more and more people acquire it just for stand shooting. Small weight, relatively small return, reliability - all this makes weapons really successful acquisition. A long trunk allows you to fire on a distance, proceedable for some analogs - for example, for smooth-bore "Saiga".
Weak returns (compared, for example, with conventional turning guns) allows you to teach to shooting teenagers and women, making the shooting of a family hobby.
Fast change of ammunition
A gun can boast another interesting feature, which not all semi-automatic people possess.
Designers provided the ability to quickly change the ammunition. By using a special switch, you can overlap the cartridge feed from the store. Due to this, after the shots, the shutter remains open, and a suitable cartridge can be attached to the cartridge.
Tuning
But the possibilities for tuning here are quite limited. Of course, the most obvious is the installation of additional sighting devices - collimator. Perfectly suitable as ordinary and diopter. In any case, the ease of aiming increases sharply.
Also, a luminous flying can be installed on the trunk, a substantially facilitating aiming at dusk.
If you wish, you can purchase and install an extension cord store. Yes, the weight of the weapon due to this will increase slightly. Also, the center of gravity is also slightly shifted - it will have to get used to the gun again, so it is advisable to carry out modernization immediately after purchase. Thanks to this improvement, the hunter gets the opportunity to make not 5 shots without recharging, but to 8 inclusive. No longer allows existing legislation. However, three additional cartridges may be very useful in various situations.
Choose a suitable ammunition
By purchasing the MC 21-12 gun, it is worth remembering: now it is impossible to use folder and metal sleeves. Folder often lead to doss or get stuck when choosing. However, they are not found on sale for a long time, so there will be no problems here.
Brass sleeves are not used due to the fact that the discarders designed to work with plastic sleeves sometimes do not capture them: the absence of a quick recharge when hunting for a large game is a very unpleasant thing that can cause serious consequences. In addition, collect discarded brass sleeves, having a fairly high cost, is not always obtained.
Therefore, a high-quality plastic product becomes the only successful choice. Thick and high skirt is only a plus. Before charging, the cartridge is preferably skipped through the calibrator.
Powder falling asleep, according to the instructions. The fraction and the canine can be used without restrictions, and bullets, as already mentioned above, you can use only podkalibers, so as not to cause serious harm to weapons.
Conclusion
Our article comes to an end. Now you know enough about the semi-automatic hunting rifle of MC 21-12, its history, pluses and minuses. So there will be no problems when choosing, it will not arise - each reader will easily decide, it fits this rifle or give preference to another.
The MC-21-12 gun has been produced for almost 60 years and is truly a unique design. In addition to him, there are no hunting smooth-bore weapons in the world with a system of rolling back. Reliability of weapons is confirmed by the volumes of release. To date, more than 300 thousand copies of this rifle have been released at the Tula Plant.
The MC-21-12 gun with a single-tier construction, which will be discussed here, was originally developed for the conduct of fishing and amateur hunting on various animals in a wide range of climatic zones. The use of weapons is not recommended in a wet tropical climate.
History of creation
The official date of creation of weapons is considered to be 1958, when a group of designers of the Tula CSCIB led by V.A. Nikolaev has developed several new models of hunting rifles. During the development, some constructive and design solutions were used in Browning Auto 5 and Breda Antares rifles.
The full name of the hunting gun MC-21-12 is decoded as follows:
- MC is a model created in the CCIB Bureau (the Central Bureau for the creation of sports and hunting arms existed in the USSR);
- 21 - model number;
- 12 - Caliber barrel.
Device
The design of the gun is built on the return scheme at a long progress of the trunk. The opposite movement of parts is provided by the spring. The barrel is fixed on a bait with a special coupling and guide flames.
To improve the cumination of fire and enhance wear resistance, the inner surface of the barrel channel is chromed and has a narrowing to the dulular slice (choc).
The difference between the diameters in the casino and the bunny parts is 1 mm, which is a very large indicator.
Optionally, the nozzle can be installed on the barrel with a smaller stroin amounting to 0, 5 and 0.75 mm. On the top of the trunk there is a bar, which increases the stiffness of the structure and provides heat sink.
At the rear of the trunk, a shutter with a sliding design is installed. Fixation is carried out using the stop performed on the gate. When the shutter is closed, the emphasis shifts vertically and enters a special guide hole made on the treasury part of the barrel.
The overall work scheme of automation is borrowed from. No more than 15% of the power of the shot is used to work automatics.
For the manufacture of lodge guns can be used or beech. The return spring is located in a deaf canal drilled in the goose tree.
The moisture is condensed inside the channel, which leads to corrosion of the spring and its jamming. Experienced hunters disassemble and dried the butt guns of MC-21-12 immediately after returning from hunting in rain or wet air.
The fire mechanism is installed separately along with the feed tray and is intended only for single shots.
The reserve of cartridges is located in the store having a shape of a long tube, and located in the Golf-21-12 rifle box. The store is equipped with a swivel cutter that closes the cartridge channel.
In the design of the gun there is a safety element with a flag switch. When the state is on, the checkbox is located vertically and closes the recess, filled with paint red.
In addition to MC-21-12, the use of the flag fuse on hunting weapons is not found. The weapon has an additional safety device that will not allow the shot at an open gate.
Before the first shot, it is necessary to push the shutter back until it is represented into the limiter. At the same time, he will automatically shoot the trigger. The shutter itself will be fixed in this position by the lever available in the construct of the feeder.
Then the arrows should place the cartridge in the cartridge guide cavity, and drown the latch lock. The shutter will rise under the influence of a compressed spring into the front position and engage with the barrel.
After that, you should releasing the button of the retainer, which will allow you to shift the feed tray until it stops. Then rotate the fuse flag in the horizontal position and the MC-21-12 rifle is ready for the shots.
Immediately after the shot, the trunk together with the shutter begins to roll back from the front point. The pulse for movement occurs as a result of the pressure of powder gases on the diacon of the sleeve, which transmits an effort to the shutter.
During the trunk, the combat and return springs are compressed.
The combat spring shall the trigger for the next shot. During the movement, the trunk frees a special stop located on the left. This stop holds the new chunks in the store.
The restoration will then be released on the right side, while the trunk and the shutter continue to make the movement of rollback. After passing the rear point, the return spring begins to move the trunk back.
At the same time, the engagement includes a feed lever, which discharges the trunk and shutter of the MC-21-12 gun. The trunk when driving extracts an empty sleeve outward and includes a feed mechanism that directs a new cartridge on the feed tray of the feeder.
Loading cartridges from the store is performed due to the force of a compressed spring. The return spring shifts the shutter portion and lifts the tray with the cartridge to the level of the barrel channel. With further movement, the shutter lines the cartridge into the state part of the barrel and presses the tray of the feeder down.
At the end of the course, the shutter comes into engaging with the barrel and the weapon is ready for the next shot. After shooting the last cartridge, the shutter does not return from the rear point of kickback.
The guaranteed resource of the MC-21-12 guns is at least 6,500 shots, which is three times the warranty shooting "Saiga". At the same time, the quality of guns produced in Russia is considered lower, rather than the weapons of the USSR.
In different years of production there were several weapons modifications:
- early model under the general designation of MC-21. This option was collected directly to CCIB small series and in piece specimens from the end of the 50s to 1964. Advertising avenues are found, in which the options are referred to the cartridge not only 12th caliber, but also under the smallest 16th and 20th. Rifle trunks had a length reduced to 675 mm and were equipped with chalnges under 65 mm sleeves;
- the serial version of MC-21-12, which went into production since 1965 at the production facilities of the Tula Armory Plant, and was produced under the cartridge of size 12 * 70 with a non-metallic type of sleeve;
- the optional option is 21-12, which had a shock absorbing rubber element on the back of the butt. From the type of butt depends on how much weapons weighs;
- version 21-12m, which had a set of nozzles on the trunk. A variant was issued with a shock absorber under the designation of MC-21-12MR. Depending on the type of delivery, a hitch may be present to the barrel with a cylindrical channel and with different narrowing parameters.
In addition to the above-mentioned basic versions, piece and souvenir guns are found, which are not the designation W and C, respectively. Under the order weapons can be supplied in a plastic or wooden case made of valuable rocks and decorated with carvings.
The main technical characteristics of the gun are described in the table below.
For external design applies:
- an ornamental pattern on flat surfaces, which is characteristic of standard execution;

Tactical and technical characteristics
Application
The manufacturer allows the use of only plastic sleeves. The use of a metal sleeve is strictly prohibited. Due to the high power of the cartridges and the use of automation, it is not recommended to use cardboard sleeves, which often take off the metal venge with capsule.
The rest of the sleeve remains in the cartridge and it must be deleted manually. To do this, the shutter is assigned to the stop back, the whole cartridge subscribed to the cartridge is removed, and the remnants of the sleeve are removed.
The MC-12 gun is recommended for running fire with fractional and cartridges at distances no more than 50 meters. At the same time, the maintenance of fire at small distances on the marsh birds is not recommended, because due to the large cuminess of the fire, there is a carcass destruction on separate fragments.
In addition, the good fitness of firing places increased requirements for the training of the arrow.
When shooting at distances of 10-15 meters, it is necessary to quickly and accurately aim, otherwise the whole charge will pass by the goal.
The optimal distance of shooting on a major feathery (Glukhary, Geese) are not less than 30 meters. When using bullet cartridges, the battle distance increases to 70 meters. The available reserve of cartridges in the store allows you to get pranks, which causes complexity when using conventional double-barreled guns.
Before using bullet cartridges, they are recommended to check. A bullet from several cartridges of one batch is taken to check and manually pushed through the barrel.
The reason for such an inspection is the unstable quality of ammunition and the scatter of the bullet diameters. When using a caliber bullet in the trunk of the "choke" type, the channel is inflated and the reduction in the combat characteristics of the MC-21-12 guns.
To check the cartridges in the kit there is a control device made in the form of a sleeve. The cartridge sleeve should freely pass through the hole of the sleeve, and the metal end of the bottom part cannot perform relative to the edge of the device. In case of inconsistency of the dimensions, the cartridges are crimped with a ring that is included in the delivery.
The center of gravity of the MC-21-12 gun is exactly in the middle of the weapon, which requires an addiction arrow.
With each shot, the trunk is thrown up to several centimeters, so the quick series of accurate shots is problematic.
To ensure a good action, weapons should be cleaned after each shooting. In case of storage, cleaning is made in preventive purposes once every three months. Alkaline solutions are used to clean the trunk channel and the cartridge, which allow to dissolve the powder nagar.
Since the shooting uses a fraction and bullets from lead, they contaminate the trunk canal. The removal of lead particles is performed using metal heroes, lubricated with weapons oil. For lubrication, it is recommended to use brand oil and-5a, which has a stability threshold minus 25 degrees. When operating under conditions of low temperatures, weapons oil is used for lubrication.
To check the health of the MC-21-12 gun, it is necessary to produce three targets shot. If at least one shot was put in parameters, then the weapon is considered suitable. Depending on the type of trunk, the arrogant of 35 meters is:
Prospects for improvement
All MC-21-12 output guns after 1991 need to be improved, which provides for the removal of burrs from all elements of the mechanism. Plastic block elements installed from the plant (shutter button and shutter liner) It is recommended to replace the analogs made of metal. The resource in plastic parts is small, especially when operating under conditions of low temperatures.
Some owners are installed on MC-21-12 an additional optical sight that allows you to improve the shooting rates lead bullets. The replacement of original sights and butts to more ergonomic structures is practiced.
The rifle of the MC-21-12 model was presented to foreign buyers at the International Fair in Leipzig in 1965. The weapon received positive feedback and, according to the results of the fair, was awarded a gold medal.
After the collapse of the USSR, the MC-21-12 gun entered the list of standard weapons for various private security enterprises (used until 2006).
Currently, the weapon consists as standard weapons for individual categories of employees of the Ministry of Forestry of the Russian Federation.
When shooting a flooring bullet from a good MC-21-12 gun, it can split 100 meters to five bricks at a distance of 100 meters.
Today, despite problems with the quality of new rifles of MC-21-12 and the emergence of a large number of Chinese production competitors, weapons remain in demand in the market. The reasons of popularity are the unique scheme of work, maintainability and high part of firing.

In domestic and foreign media, evidence of the use of the Syrian army of Russian weapons again appeared. The supply of weapons and technology of Russian production in Syria is not, however, from time to time there are very interesting reports on the transfer of certain new samples. So, at the beginning of this year, reports appeared on the use of the Syrian army of Sniper rifles MC-116M. In early December, this topic again became relevant: several publications published photos of Syrian snipers with this Russian production.
In general, the delivery of Russian small arms of friendly Syria is not a sensational news. Military-technical cooperation between Russia and Syria lasts for several decades, and with the beginning of the civil war it only increased. In connection with the loss of bases and warehouses with the material part, the Syrian military were forced to post new orders for this or other military products. Not later than last year, the nomenclature of the arms supplied was replenished with Russian high-precision rifles MC-116M. It should be noted that the order itself could appear much earlier, and the delay in the advent of the first evidence of the supply of such weapons is related to a number of objective reasons.

According to reports, the Syrian armed forces received a number of MC-116m rifles, which were transferred to a number of units of the ground forces. This weapon is applied in direct appointment: to defeat the living force of the enemy at distances up to several hundred meters. In addition, Syrian snipers are likely with such rifles may affect the unprotected enemy technique. The well-known characteristics of MC-116M make it possible to assume that this weapon has high efficiency when applying in cities and other settlements.
Sniper rifle MC-116M was developed by the Tula Central Design Bureau of Sports and Hunting Weapons (CSCI COO), which is now included in the design office of the Instrument Development Bureau in the mid-nineties. The goal of the new project was to create a combat version of the existing sports rifle of MC-116. Such weapons successfully applied by Russian athletes, and its main features allowed to create a combat rifle with similar parameters. By recycling new parts and changes in some design features, a sniper rifle MC-116m was created. Work on this project was completed in 1997.
Mtz-116m rifle is a non-automatic high-precision weapon with manual reloading and a store bippet designed for a cartridge 7.62x54 mm R. It uses some units borrowed from basic sports MC-116, however, for use in the construction of the structure, a store was implemented and Some other nodes designed to enhance the characteristics.

MC-116M is equipped with a "heavy" cutting trunk of a 650 mm long caliber (85.3 caliber). On the side surface of the trunk are provided by prophes, with which more efficient cooling between shots is ensured. In the bunny part of the trunk, the folded flies and fastenings for a slotted flamesteller are located. An important feature of the rifle is the construction of the trunk fasteners. The trunk is performed freely posted and is held in its place only by contact with the trunks. The rifle bed is designed in such a way that in all its length it does not contact the side surface of the trunk. This makes it possible to ensure the constancy of the oscillations of the trunk when the shot, which is easier to consider in the shooting.
The barrel is fixed in a cylindrical border, located in the back of the lodge. The design of the box has a number of features characteristic of weapons with manual recharge. The right side surface provides a window for emissions of the sleeves, in the bottom - the receiving window of the store. In the back of the box there is a curly cut, along which the shutter handle is undergoing during the preparation for the shot. On the upper surface of the receiver box, attachments are provided for sighting devices. Rifles of the early episodes were equipped with a "swallow tail" type. Currently, the rifles are equipped with picatinni planks that expand the nomenclature of compatible sights.
The gate of the weapon is made longitudinally sliding and turns around its axis in the extreme front position. Locking the trunk before the shot is made with the help of two combat battle stops. To control recharge on the gate, there is a M-shaped handle. The form of the latter makes it easier to work with a shutter, and also does not impose restrictions on the design of the sight.

The shock-trigger mechanism is divided into two parts. The drummer and the combat spring are mounted inside the shutter. The shooting of the drummer is made when the shutter movement and the resolution of the new cartridge. A curious feature of the shock mechanism is the tail part of the drummer, which, when wearing a weapon, performs from the rear end of the shutter and serves as an indicator. The trigger is made on a separate basis and provides unlocking the drummer, followed by a blow to the cartridge cap. The trigger has several adjustments. The shooter can change the move of the trigger in the range from 0.5 to 2 mm, the descent force changes from 0.5 to 2.55 kgf. A non-automatic fuse is included in the trigger, the flag is located before the trigger. In the plot, the fuse blocks whisper.
The bippet is carried out from removable boxes on 5 or 10 ammunition. In this case, the package includes stores 6V1 by 10 ammunition. The store is placed in the lower window of the lodge and fixed using the appropriate latch.
All MC-116M rifle aggregates are mounted on a wooden bed with adjustable butt. For greater convenience, the arrow provides mechanisms to change the length of the butt and height of the cheek. There is also the possibility of moving the neighboring in vertical and horizontal planes. The length of the butt is adjustable within 30 mm, the vertical deviation of the hut is as limited to 30 mm up and down, side - up to 6 mm. The cheek of the butt can rise by 30 mm and move on both sides by 6 mm.
The basic set of Sniper rifle MC-116M includes an optical sight of the POSP-8X42L. If necessary, the arrows can use other aiming devices fixed on the bar of the receiver box. To improve the accuracy of the fire, the rifle is also equipped with a two-legged compartment of the MC116M C64 mts116m, adjustable by the focus on the butt and the contamination device MC116M SB6.
Rifle MC-116M with an empty store and without aimicual devices weighs about 6.5 kg. Length of weapons without inflatable devices - 1250 mm. The minimum distance from the middle of the trigger to the slotter is 340 mm.
According to the manufacturer, the effective rifle shooting range reaches 700 m (according to other data, 800 m). It provides sufficiently high accuracy. According to some data, when applying high-quality cartridges 7.62x54 mm R "Extra" is ensured by the accuracy of the order of 1 Moa.

According to reports, already at the end of the nineties, the Sniper rifle MC-116M went into mass production. Nevertheless, specific characteristics, labor-intensity of production and tactical niche affected the rate of production. The rifles of this type are made by small batches by order of various structures from the Ministry of Defense, the Ministry of the Interior, the Federal Security Service, etc. Thus, the total number of MC-116M rifles produced may not exceed a few hundred.
According to the manufacturer, the rifle can be equipped with the trunks of two types calculated for different ammunition. The main ammunition is the domestic 7.62x54 mm R. In addition, weapon production is possible under the cartridge 7.62x51 mm NATO. In this embodiment, the MC-116M rifle is offered for export.
In early 2015, first photos and videos appeared, on which the arrows of the Syrian army with rifles MC-116m were depicted. This was the first evidence of the delivery of such arms of friendly Syria. In the future, Russian high-precision rifles have repeatedly "melkali" in new chronicles of war. Details of the use of such weapons were not specified, but it can be assumed that its use allows you to effectively affect the lively enemy strength, to maintain the advancing units and solve other combat missions.

Sniper rifle MC-116M is the further development of sports weapons, which made it possible to achieve high characteristics. This weapon has long been used by Russian military and security forces, but mainly applies only during training and exercises. The supply of rifles in Syria made it possible to check this weapon in a real conflict. Judging by the fact that the exploitation of such weapons continues, MC-116m has proven itself well, and the original approach to creating a rifle was fully justified.

The cartridge located in the store and moving back along with the trunk and the shutter is delayed by the left stop.
The next moment the protrusions of the trunk and the shutter will free the right stop of the patron. The trunk and the shutter continue movements back. In the extreme rear position, the shutter will be held by the feeder lever. And the trunk under the action of its spring, moving forward, reflects the shooting sleeve through the side window of the cover: the protrusion of the trunk, pressing on the left stop, heats it in the grooves of the box.
The released cartridge under the action of the store's spring is moving to the feeder 50 (Fig. 7), pressing the chosen liner with the feeder latch, as a result of which the shutter is released, which begins to move forward. The feeder, rotating, raises the cartridge, and moving forward the shutter sends a raised cartridge into the cartridge. The next cartridge is delayed in the store right-wing patron.
With the approach of the shutter to the extreme front position, it presses the right stop of the cartridge, and the released cartridge under the action of the store's spring is moving back to the cartridge stopper 23 in the gate.
In the process of shot, when the shutter movement in the rear position, the trigger 54 will turn to the axis to the extreme lower position. Combat "A" and disbanded "b" The jackets of the juro will be at this moment under the appropriate hints of the descent and separator.
The next moment, with a shutter shutter in the front position, the unused hook of the smoke will rise to an appropriate headset. In order to make the next shot, it is necessary to release the descent 59. At the same time, the descent under the action of the spring will turn on its axis, and the trigger under the action of a combat spring will jump off the leakage of the disintegrator in the warhead.
Rouge is ready for the next shot.
After the end of the shooting rifle, be sure to discharge.
To do this, put a descent on the fuse (Fig. 2), climb the feeder and, at the same time, clicking on the cartridge limiter and cartridge, remove the cartridges from the store alternately.
To remove the cartridge located in the chamber, the shutter is back. Holding the shutter with a hand, render it to the front position, then take back again. Making sure that the cartridge in Patronic Peg, return the shutter to the front position.
If, but the shooting time must be replaced with a cartridge located in a chamber, put a shut down on the fuse, turn off the cartridge shutter shop, remove the shutter back by the handle, remove the cartridge and put the new chain. The shutter come forward.
Turn on the flow of cartridges from the store by turning the clipboard.
Before shooting the fuse box, place horizontally.
6. Safety instructions
Before using the gun, the hunter is obliged to explore safety rules when handling weapons and ammunition.
Remember! Never send a gun on a person or pets.
The gun should be stored uncharged, with a slosen curcken. Sunpashers store out of the reach of an unavailable place.
When shooting with bullets, in the emissions of inflating and breaks of the computers, the diameter measured by the body of the bullet without taking into account the centering edges should be less than the diameter of the muzzle narrowing. For round bullets, this rule is easy to check the free passage of the bullet through the muzzle narrowing.
make disassembly of a charged rifle;
make a replacement of duct nozzles of a charged gun;
apply cutting cartridges when checking the interactions of parts and mechanisms of a gun by moving the barrel or shutter manually;
apply the cartridges in which the largest value of the maximum pressure of powder gases of more than 65MP (65MR) developed in the barrel channel (65mR);
