Description

The utility model relates to weapons technology, namely a single-barrel firearm without a magazine.

The prior art knows weapons that have been converted from weapons with a detachable magazine to satisfy legislative requirements prohibiting the use of firearms with a magazine for certain categories of users (US patent No. 6212814, F41C23/12, F41A11/00, publ. 04/10/2001, patent Germany DE20214354, F41C3/00 published 02/06/2003, RF patent No. 2787065, F41A9/00, published 12/28/2022). However, no technical solutions are known from the prior art that would allow converting a gun with an under-barrel tubular magazine into a gun without a magazine.

The closest technical solution adopted for the prototype is the single-barreled multi-shot self-loading shotgun MP-155 (Maksimov Yu. MP-155 to replace the MP-153, Part 1 // Hunting - 2014. - No. 1.

In this case, the tube serves as a magazine and also serves as the basis for attaching the forend.

The presence of a magazine in the design of a well-known gun prevents its use by users with less than two years of experience in owning firearms, since in accordance with current legislation, citizens of the Russian Federation are not allowed to purchase a smooth-bore long-barreled firearm for the purposes of self-defense or hunting before the expiration of the first two years of ownership of a long-barreled smooth-bore firearm a weapon with a magazine.

The purpose of the utility model is to expand the arsenal of single-barreled shotguns that do not contain a magazine.

The technical result consists in creating a single-barreled shotgun without a magazine based on a repeating shotgun with an under-barrel tubular magazine, allowing inexperienced shooters to master the skills of handling weapons, which will further facilitate the process of starting to use multi-shot weapons with an under-barrel tubular magazine and increase operational safety.

The problem is solved due to the fact that the gun contains a barrel with a chamber, a bolt, a forend and a tube permanently installed under the barrel, in which, according to the utility model, the internal cavity of the proximal part of the tube has a permanent barrier in the form of a local narrowing of the internal diameter of the tube. The proximal end of the tube can be closed with a plug.

The claimed gun will be further examined using the example of a smooth-bore long-barreled gun, converted from a self-loading multi-shot gun with an under-barrel tubular magazine, in which the movement of the moving parts of the gun is carried out by a gas engine. Nevertheless, the claimed utility model can be used for a gun in which the movement of the moving parts of the gun is carried out manually by the user, for example, for a pump-action shotgun.

The essence of the utility model is illustrated by the following drawings.

Figure 1 is a general view of the gun with the bolt retracted to the rearmost position.

Figure 2 – front cross-sectional view of the tube

The gun contains a barrel 1, a bolt 2, a tube 3, a forend 4, a tray 5 for feeding cartridges into the chamber 6. The forend 4 is fixed to the tube 3. The tube 3 is permanently installed under the barrel 1 and is located parallel to the barrel (Fig. 1). The internal cavity of the proximal part of the tube has a permanent barrier in the form of a local narrowing of the internal diameter of the tube. The proximal end of the tube is closed with a plug 8, which is designed to prevent dirt and foreign objects from entering the internal cavity of the tube 3.

Making a permanent barrier 7 in the proximal part of the tube 3 in the form of a local narrowing of the inner diameter of the tube blocks the placement of cartridges in the internal cavity of the tube 3 and prevents its use as a magazine.

Local narrowing can be performed using a rolling operation on appropriate equipment (Fig. 2). The significance of the local narrowing of the internal cavity of the tube depends on the material and thickness of the tube. For example, the more ductile the metal, the more it is necessary to reduce the internal diameter of the tube.

Also, local narrowing can be performed by installing a washer-type part into the internal cavity of the tube using a permanent connection, such as welding, flaring, etc. The dimensions of the part (thickness, hole diameter) depend on the characteristics of the part material. The more susceptible the material is to destruction and change in shape, the greater the thickness and/or smaller the hole diameter of the part should be.

The gun works as follows.

To fire a shot, you must manually move the bolt 2 to its rearmost position. The bolt 2 is delayed, opening tray 5. After this, a cartridge (not shown) is manually fed into tray 5. Next, the interceptor button (not shown) is pressed, the bolt 2 is released, and the moving parts of the gun move forward. In this case, tray 5 with the cartridge rises, the cartridge is placed on the chambering line and bolt 2 sends the cartridge into chamber 6. The gun is ready to fire. After the shot is fired, the bolt 2 is retracted under the action of a gas engine (not shown), the spent cartridge case (not shown) is removed from the chamber 6 and thrown outside the gun. The gun is ready to accept the next cartridge.

Thus, in the claimed gun without a magazine, created on the basis of a self-loading multi-shot gun with an under-barrel tubular magazine, the process of ejecting the cartridge case after a shot is fully automated, which minimizes manual manipulation, reduces the time for reloading/feeding a cartridge and increases the operational characteristics of the gun.

The creation of a permanent barrier in the form of a local narrowing of the inner diameter of the tube in the internal cavity of the proximal part of the tube makes it possible to create a gun without a magazine based on a multi-shot gun with an under-barrel tubular magazine for users with less than two years of experience in owning smooth-bore long-barreled firearms.

The creation of a gun without a magazine on the basis of a repeating gun with an under-barrel tubular magazine provides an opportunity for novice shooters to gain experience in owning firearms and become familiar with the design, basic principles of operation and operation of multi-shot weapons with an under-barrel tubular magazine. Therefore, after obtaining the experience required by the legislation of the Russian Federation in purchasing multi-shot weapons with an under-barrel tubular magazine, the stage of user adaptation to the new weapon is significantly reduced, which increases operational safety.
