MC 21-12. The hunting gun is MC 21-12. Characteristics, instruction, photo

Today, spoiled with a large variety of semi - automatic smooth - bore weapons, even Russian hunters of the old formation began to forget that at one time most of them had a longed-for dream - Tula self-loading rifle MC 21-12. Today, this single-barrel, despite the fact that it continues to be produced by TOZ, is considered bad and outdated in all respects. Especially for young hunters, for whom hunting is just a tribute to fashion or a kind of business corporate. In such circles, the gun is not an instrument, but an indicator of the social status of its owner. In this article, we will not praise the honored veteran of the Soviet arms industry. And we will not pour mud on him, listing all the shortcomings. The purpose of the article is to look at the hunting weapon of MC 21-12 from the position of the modern fishers, who fully had time to taste the variety of both imported and domestic "self-loading".

Weapon History

Probably about the gun of MC 21-12 for its more than fifty years of history did not write only lazy, so we in this article simply recall the most important events in the life of these weapons and just briefly dwell on its technical characteristics and design features. This "self-loading" is truly a cult for many hunters-fishers of the past, so even this information that is full of nausea may be of use to someone, or, at least, theoretically interesting. So, the gun MC 21-12 (the photo is shown above) was created by designer Nikolayev VA. It is a self-loading single-barreled weapon for commercial and amateur hunting. Initially, in the period from 1956 to 1964, this model was manufactured in TsKIB SOO. In addition, until 1965, the MC 21 produced 16th and 20th calibers. At the Leipzig Fair, held in 1965, this model was awarded the Gold Medal. In the same year, the release of the gun was transferred to the TOZ. Until today, MC 21-12 was produced only in the twelfth caliber.

Description of units and mechanisms

Automation weapons based on the principle of rollback with the release of the spring-loaded mobile barrel and the gate mechanism sliding along the Browning system of the 1905 model. Recharging is carried out as a result of using a fairly long stroke of the trunk at the time of its movement to the rear, and then to the forward position. Removable barrel length of 750 mm has a sighting bar ventilated type. The chamber is 70 mm. Details USM, muzzle channel and the shutter are chrome plated, this greatly facilitates the care of the weapon, and also increases its longevity.

The barrel is locked by a sliding slide. Its fighting stop is fixed for the opening of the shank. The progenitor of this model, "Auto-5" produced by Browning, this stop has a rectangular shape. So, in one of the issues of the magazine "Hunting and hunting. "Tsarkov V. (Honorary member of the MOAD), describing the typical delay for the guns MC 21-12 - the disconnection of the bolt and barrel during the shot, focused on the round form of the abutment as the cause of this defect. Of course, the truth is in the words of the old hunter, but it should be understood that the change in the form of the combat emphasis, so to speak, the simplification of the design, is due to the need to bypass the patent rights of the Browning construction. In addition, we should also take into account the time of the release of the gun, in the fifties, no one would allow the production of an unfinished model. The causes of problems with weapons, subject to the elimination of design flaws, are usually hidden in the quality of assembly and manufacturing. Also, we should not forget about the quality of ammunition.

The hunting rifle MC 21-12 has a trigger type ASM, assembled on a separate base. Extraction of sleeves is carried out at the moment of movement of a trunk in a forward position. With an unlocked channel, a shot is not possible.

Short description

Shotgun MC 21-12 (the photos given in this article will help the reader to form his opinion about this weapon) has a barreled tubular magazine with a capacity of four cartridges. The body serves as a guide for the movement of the trunk. Cartridges from the cage are fed by the bolt, when it is moved to the front position. The store is filled with one ammunition, through the window at the bottom of the receiver. If necessary, the shooter can block the supply of cartridges from the cage, including the cut-off device mounted on the left side of the box. The non-automatic safety device of the flag type carries out the locking of the trigger hook. A curious feature is the possibility of changing the flag to the left. Applied MC 21-12 pistol shape. The bed is removable, it is fixed by a spring-loaded nut on the body of the store.

Tactical and technical characteristics

The weight of the weapon is 3.2-3.4 kg. The overall dimensions are 1285x65x200. The force of descent is 1.5-2.5 kg. Sometimes in the literature indicate no more than 3.7 kg. If compared with modern self-loading rifles based on aluminum alloys, then this is quite a lot. However, MC 21-12 is completely made of quality Tula steel, it has a large margin of safety. The manufacturer gives a guarantee for 6500 shots. If the reader doubts whether this is a lot or not, then an example is Izhevsk "Saigu", the guarantee for which is only 2000 shots.

However, let's return to our rifle. The safety factor of this weapon is so great that with proper care it can serve for a very long time. Breakages even after ten thousand shots are very rare. Here is such a reliable model - MC 21-12. The characteristics of this gun speak for themselves. Try to produce 10,000 shots from the imported "self-charging" basic equipment, it is unlikely you will succeed. Owners of this gun should take into account one feature - you can use only ammunition with plastic sleeves. The manufacturer categorically prohibits the use of metal and paper cartridges.

Everyone will not be nice

Let's consider one more unique side of model MC 21-12. Reviews and the diversity of opinions about it, probably, are inferior to the sharpness of the discussions of the opponents and supporters of the Saiga. In fact, this applies to any rifle. After all, we are all different. Sex, age, type of higher nervous activity, social status and income level, experience in handling weapons and hunting, the presence or absence of desire / ability to do something with one's own hands, etc. All of these factors will inevitably affect the perception of phenomena and objects , Making them special for each person. Well, and if we take into account the bright individuality of any model of weapons that is not manufactured on stream lines of CNC machines, then it becomes clear: one can not expect a unanimous opinion from such a diverse hunting community about the very ambiguous shotgun MC 21-12.

Tips experienced hunters will help to deal with the main problems of this weapon. They are known to many, and they are all curable in a home workshop. Simply put, any hunter who "grows out of the right place" with his hands, having a couple of free evenings and a minimal set of tools, can make his semiautomatic machine absolutely reliable and trouble-free to use.

What to do: buy a foreign car or support a domestic manufacturer?

For those who do not want to think and fitter, it's easier to buy imported "self-loading". Such single-barrel hunting rifles are beautiful, light and almost trouble-free. For one small defect: the price of such weapons can be several times, and even an order of magnitude higher than the cost of our MC 21. There are also so-called budget models, but their quality can not be compared even with our "handicraft" production, it's money thrown to the wind .

Today, the whole world is again affected by the economic crisis, the cost of imports is steadily growing, so that their supplies are declining. The domestic gunsmiths have an excellent chance to occupy the emerging niche of this market not only in Russia and CIS countries, but also in Europe. Agree that it is better to purchase inexpensive inventory of Russian gunsmiths and, if necessary, slightly refine it, than to remain without any hobby at all. Turkish consumer goods problems do not solve - their self-loading single-barreled rifles and more expensive than domestic ones, and with the quality of similar problems, although commercials repeat the opposite.

MC 21 was appreciated by experienced hunters in the past, and now it is bought by those who can not afford expensive weapons, or experienced connoisseurs. Of course, this gun has modern competitors, such as the legendary "Murka" MP-153, TOZ-87 and "Bekas-auto." "Snipe" and "Murka" are also very ambiguous representatives of hunting semiautomatic devices, but the TOZ-87, if made at a better level, could become the best domestic self-loading rifle. The title of "people's" is rightly occupied by MP-153, however its cost is 1.5 times higher than MC 21-12, and compared with it, this model is often inferior to barrel production, has a narrow inconvenient aiming bar, and is characterized by misalignment of muzzle Attachments. The guns of the Tula gunsmiths are traditionally distinguished by excellent trunks and a remarkable fight. Many hunters who purchase MC 21 today make their choice precisely because of these qualities.

Debugging and debugging by the method of Azarov A.: automation system

In one of the issues of the magazine "Hunting and hunting. Economy "was published article A. Azarov, in which he gives recommendations on the debugging of guns MC 21-12. Below we will consider what the author advises.

A huge role in the operation of automation is played by a recoil system. Sometimes guns come on sale, the trunks of which do not have a chamfer in the brake clamp ring. In such copies, a pair of buffer rings are placed on the store. The author of the article recommends that owners make small chamfers on the rings themselves, otherwise the mechanisms will begin to scratch with sharp edges of each other, in this case the chips will be literally removed. In addition, badges on the cage will interfere with the functioning of the recoil system.

The process of locking the trunk also has a decisive role in the operability of the automation. The firing stop of the bolt, being in the forward position, rises up and enters the window of the shank of the trunk. Its cylindrical part can be attached to the walls of the window unequally densely. It is necessary to watch the watch when the shotgun is assembled with the cover removed, the tight fit must be only in the rear part. If it is not there, then during the shot, the emphasis will make a work on the cutout of the shank. On some specimens, this gap can reach one millimeter - this is unacceptable. Now in the arms shops you can buy spare parts for the model MC 21-12, so to speak, for all occasions. Thus, combat supports with cylindrical part diameters from 10.7 to 11.9 mm are produced. It is necessary to eliminate this shortcoming by selection. Strong interference and poor polishing in this part are also unacceptable, since the shutter and barrel will not separate.

Possible malfunctions, debugging and debugging of the gate mechanism

On top of the end of the bolt on the left there is a retainer, and on the right there is an ejector. It is necessary visually and by touch to check the quality of grinding, in the presence of burrs, carefully remove them with a velvet skin. If the insert on the gate is plastic, it is better to replace it with a metallic one, in order to avoid staining. In addition, it is necessary to check the density of the mechanisms. Do not allow large lateral play of the shutter in the grooves of the box. If it is shaken from side to side, it should not be slouched, otherwise it can lead to the breaking of mechanisms. In addition, check the feeder tray. It should be on a par with the store window (the offset is unacceptable), there should not be any burrs on it, as the cartridges will be braked when sliding along the tray. All mechanisms need to be polished, otherwise ammunition will be clinging to unevenness when filing. Cartridges for MC 21-12 should also not have defects on the outer surfaces of the sleeves.

In the assembled state, the lower right-hand projection of the shutter must press the right stop to avoid delays in the release of ammunition from the cage to the stop. Sometimes in badly adjusted weapons he jumps. In this case, the right stop is obtained not recessed in the groove on the box. This leads to the jamming of the cartridge in the cage. This can also happen after intensive use of the gun, when the barrel and the end face of the shock absorber are broken. As a result, the bolt will start to go further than the put. In this case, the repair is reduced to feeding back and fixing the shock absorber forearm. Under it, you can glue a specially machined ring.

In the event that the bolt is slightly retracted, the right stop should fix the ammunition in the cage, resting against the flange of its sleeve. If this does not happen (mud in the groove or the spring is broken), then the cartridge falls to the ground. This occurs when the bolt, moving forward, sends another ammunition when the tray is raised in the chamber, and the next after it drops out under it. This can also occur with an understated diameter of the liner flange. If the latch of the feeder lingers in the groove at the moment of retreat, the tray rises, and the barrel, moving forward, drowns the left stop and releases the cartridge, which as a result falls to the ground.

Debugging and debugging of the receiver

As a result of the fact that the end of the lid protrudes above the box, the rifle's forearm loosely sits on its proper place, the locks in this case may not enter the ends of the grooves. As a result, the bed spins on the cage. In this case, it is necessary to adjust the cover of the box. Sometimes there are instances of which the end collar can be screwed to the thread with a skew, as a result, the barrel will be braked when rolling back on the inner walls. In this case, it is necessary to clean the wooden surface in these places. If this does not help, then you need to re-install the clip.

Also it is necessary to pay attention to how the fighting spring is installed in the USM. Does the right wall interfere with her work? In the assembled position, remove the lid and check if the trigger pushers press the trigger. It should be ensured that the support (front) washer of the bed is not moved relative to the hole, otherwise it can damage the thread on the end of the cage and will loosen its fastening.

General debugging

There are instances in which the sleeve flange is strongly deformed after the shot. This is due to poor fitting of the locking mechanism. It is possible to detect this defect only after firing.

Before using the gun it is necessary to determine the smaller diameter of the brake spring. With this ring, put it on the tube of the store. Also, follow the velvet nail file to smooth out the sharp parts at the last coil of the spring. In this case, the tube of the cage will not be scratched.

If the bolt is twisted, make sure that the stem and spring are not seized in the shank of the box. If something prevents them, you should eliminate the cause. In addition, it is necessary to check the operation of the ammunition cut-off. If you turn the checkbox anti-clockwise, the cartridge should stop at the cutoff while pulling the shutter. And in the future do not reach the left stop.

Shotgun MC 21-12: price

In connection with the fact that this weapon has already been discontinued, it is difficult to find it on the shelves of arms stores. However, it is not necessary to despair, they still exist in the storerooms and, if desired, they can be ordered, although it will be necessary to wait a while. The disadvantage of such a purchase will be that you will not have a choice of the best among several copies. So it's better to find a store that still has this weapon. So, you decided to buy a gun MC 21-12. The price of such "self-charging" will be about 15 thousand rubles, but if you want you can buy weapons in the secondary market. In this case, its cost will be much lower.

Summary

Many young hunters are frightened by the principle of automatics in this gun - a rollback of the trunk. However, do not forget that this scheme was the only one working until the end of the 1980s. The first serial semi-automatic rifles with a gas removal system appeared only in 1990. It took little more than twenty years - and on the shelves of arms stores you can see the slender rows of gas discharge "self-loading", and the system with the barrel re-entry is represented only by the MC 21-12 model. The responses of the Arctic hunters about this gun are unequivocal. It turns out that in these difficult weather conditions there has never been and still is no alternative to this weapon. The debugged MC 21-12 at an autumn temperature of up to twenty degrees of frost has proved to be an accurate and reliable assistant. Until now, it is used in the north for both deer and geese hunting, because a very sharp and heapy battle allows you to beat a bird at distances of up to seventy meters.

Today the gun of MC 21-12 is still in demand by hunters. Often a new copy works flawlessly, refuting evil slander, directly "out of the box". True, there are also reverse situations, when the gun does not want to work at all. However, in this case, it is enough to spend an hour or two time, armed with a fileter to make it work like a clock. Given an attractive price, the gun is acquired by both skilled hunters and beginners. Especially valuable are copies of the Soviet assembly. Despite their considerable age, they still please their owners to this day.

So to write off the gun MC 21-12, despite its shortcomings, from the arsenal of domestic hunters until we hurry ...
