Description

The proposed design relates to the field of weapons for hunting, namely, to rifled self-loading weapons designed to defeat a large beast at distances up to 300-400 meters.

Currently, in the world, and in Russia in particular, there is an increase in interest in the above weapons, in the above hunting, which is explained, firstly, due to the significant increase in the number of people who can afford this type of hunting, and, secondly, due to a significant increase in the number of private landscaped hunting farms where this type of hunting can be carried out in a civilized manner.

A known design of 9 mm. hunting self-loading carbine for shooting at a large beast (1).

The disadvantages of this weapon, reducing its market attractiveness are its high cost, increased sonicity of a shot due to a powerful cartridge and the use of reliable, but outdated technical solutions.

A known design of 9 mm. hunting self-loading rifled carbine for firing at a large beast (2).

The disadvantages of this carbine are the same as (1).

Famous domestic 7.62 mm. self-loading hunting carbine (3) converted from AKM combat machine.

The disadvantages of this carbine, despite the significant reduction in the cost of its manufacture due to the maximum technical and technological compatibility with AKM, are, firstly, the inability to hunt a large beast at distances of 300-400 m., Secondly, the increased sonicity of the shot, and, thirdly, the use of reliable, but outdated technical solutions.

The above carabiner (3) is taken by the authors as a prototype developed as the closest in technical essence and achieved technical effect.

The task that was solved when creating the developed 9 mm. self-loading hunting carbine, was an improvement in a number of operational characteristics when using a carbine for hunting large animals at a distance of 300-400 m.With the simultaneous reduction in the cost of its manufacture through the use of new, unconventional technical solutions for this type of hunting weapon.

This problem is solved in the proposed design of self-loading 9 mm. a carbine containing a receiver with a barrel and a sleeve for venting gases on the barrel, a receiver cover, a spring-loaded bolt frame with a rotary bolt and a gas piston, a trigger mechanism that encloses the barrel, a casing cantileverly mounted on the gas outlet sleeve with an opening for the bullet to escape, sighting fixture mounted on the casing, fuse type flag, magazine for cartridges, forend and butt.

New significant features of the proposed design are:

- introduction to the structure of the enclosure covering the barrel;

- cantilever mounting of the casing on the gas outlet sleeve;

- the execution of the casing with the muzzle of the barrel with a hole sufficient for the departure of the bullet;

- installation on the casing sights.

In the particular case of the execution of a carbine, on the barrel under the casing, between the gas outlet sleeve and the muzzle of the barrel, a perforated sleeve is fixed in the longitudinal direction for additional support of the casing.

A new significant feature in the particular case of execution

the carbine is mounted on the barrel under the casing between the gas outlet sleeve and the muzzle of the barrel perforated in the longitudinal direction of the sleeve for additional support of the casing.

According to the authors, the above, new features of the main paragraph can be classified as significant, because providing increased performance of the rifle, such as reducing the likelihood of burns to the barrel, especially for inexperienced shooters, improving the aiming conditions by reducing the effects of glare, for example from snow or puddles on the underlying surface of the earth, reducing the impact of the sound of a shot on the gunner’s hearing, at the same time simplify the design and the technology of its manufacture, which leads to lower sample costs.

In addition, it should be noted that in the proposed design, the installation of the sights not on the barrel but on the casing is technically justified, because when shooting at a large beast at a range of 300-400 m. in comfortable conditions, the shooters can also use an optical sight, which is mounted, as a rule, on a guide made on the receiver of a weapon.

The proposed design is presented in the attached drawing.

The self-loading hunting carbine comprises a receiver 1, a barrel 2 fixed therein with a gas outlet 3, over which a gas outlet sleeve 4 with a gas outlet 25 is fixed, and a cantilever casing 5 with an opening 27 fixed thereon enclosing the barrel.

Inside the receiver 1 there is a bolt frame 6 with a gas piston 7 and a return spring 8, a rotary type bolt 9 with locking protrusions 10, for interacting with recesses 11 in the receiver 1 and a spring-loaded striker 12 with a service spring 13.

Also in the receiver placed trigger, containing the trigger 14, whisper 15 and fuse 16 in two positions, for example, flag type.

In addition, in the lower part of the receiver 1 there is a neck 17 for installing a cartridge magazine 18, and a handle 19 and a butt 20 are fixed at the rear of the box 1.

Outside the casing 5 is rigidly fixed, for example, by welding the rear sights 21 and the front sight 22 of the sights.

On top of the receiver 1 is closed by a lid 23.

In the particular case of execution on the barrel under the casing between the gas outlet sleeve and the cut of the barrel 2 can be fixed perforated in the longitudinal direction of the sleeve 24 for additional support of the casing 5.

In the idle position, the bolt 9 is in the forward position, its locking protrusions 10 are located in the corresponding recesses 11 of the receiver 1. The bolt 12 of the bolt 9 is in the forward position, the mainspring is in the released position. The fuse box 16 is set to the “fuse” position, i.e. trigger trigger 14 is locked.

To bring the hunting carbine into the firing position, it is necessary to insert the magazine 18 with cartridges into the neck 17 of the receiver 1, put the fuse box 16 in the firing position, the trigger 14 is unlocked from the fuse 16.

Next, charge the bore with 2 cartridge. Why take the shutter frame 6 all the way back and release it.

Under the action of the return spring 8, the bolt frame 6 moves forward and protrudes the bolt 9 sends the cartridge from the magazine 16 to the chamber of the barrel 2.

At the same time, when the bolt frame 6 moves forward, the mainspring 13 of the striker 12 is cocked, and the trigger 14 with its protrusions holds it through the sear 15.

At the end of the movement of the shutter 9 under the action of the bolt frame 6 is rotated, and its protrusions 10 are installed in the recesses 11 of the receiver 1, closing the cartridge in the barrel.

The carbine is ready for a shot.

To produce a shot, the carbine is aimed at the target by means of an aiming device 21,22 and the trigger 14 is pressed, which interacts with the sear 15, the rotation of which releases the hammer 12 and that impacts the cartridge capsule under the action of a compressed combat spring 13. A shot is being fired.

Under the influence of powder gases, the bullet leaves the barrel of the weapon and the hole 27, while part of the powder gases falling into the volume between the casing 5 and the barrel 2 and when it expires through the perforated sleeve 24 loses some of its energy, which is positive from the point of view of reducing the physical impact of flowing from the barrel gunpowder gases on the arrow.

In this case, part of the powder gases after the passage of the bullet venting hole 3 in the bore of the barrel 2 is directed through the hole 25 into the venting sleeve 4 and, acting on the piston 7 of the shutter frame 6, move it back.

In this case, the bolt frame 6 rotates the bolt 9, and its protrusions 10 exit from the recesses 11 of the receiver 1.

When the shutter frame 6 with the shutter 9 moves back, the sleeve bumps into the extractor in the receiver (not shown in the drawing) and is removed from the shutter 9 through the window 26 in the cover 23 of the receiver 1.

Further, the interaction of the parts of the carbine is carried out similarly to the above when loading the carbine with a cartridge and the cycle can be repeated.

All parts and assemblies of the self-loading hunting carbine are made of the well-known structural steel of weapons production using well-known technologies using standard equipment.

Preliminary calculations showed that the proposed carbine is 10-15% lighter than the prototype, has more favorable parameters of the overpressure of powder gases on the shooter after the bullet takes off, and the cost of the new 9 mm. a hunting self-loading carbine will be 20-25% lower than its foreign counterparts.

Currently, at one of the enterprises of the Moscow region, work is underway on the industrial implementation of the developed model for a new hunting 9 mm. cartridge developed on the basis of the domestic cartridge SP5.
