Abstract

A tool for cleaning the bore of a small arms, consisting of a metal rod of variable diameter, screwed onto the ramrod with one end, characterized by the presence of a square section tip and a hyperbolic assembly at the opposite end of the rod, which, when used together with a rag or tow, ensure uniform movement of the structure in the small bore in order to remove combustion products.

Description

The utility model relates to accessories for cleaning the barrel of small arms.

Currently, a pencil case with accessories [1] is included in the set of small arms, a component of which is wiping, which differs from similar domestic devices only in caliber.

Rubbing with rags or tow is used to clean the barrel of a small arms as follows. For cleaning the bore, it is passed through the tow rubbing slot or rags; the ends of the tow should be shorter than the rubbing rod, and the thickness of the layer should be such that the rub with tow is introduced into the bore with a small effort of the hand; pour a little liquid gun grease on the tow and gently wrinkle the tow with your fingers. Insert ramrod with rubbing and tow in the bore. With one hand holding the muzzle of a machine gun (machine gun), and holding the pencil case with the other, smoothly, without bending the ramrod, advance it along the entire length of the barrel bore several times [1].

The disadvantages of the above process:

- repeated movements are not scrubbed with a ramrod, but “smeared” with dirt in the barrel of a small arms weapon;

- with repeated movement of the ramrod from the edge of the barrel to the chamber, scratches and chips of the edges of the grooves appear on the mirror of the channel.

In foreign armies, they use a different technology for servicing weapons [2] and use instead of rubbing vishers [3, 4] - an invention close to the claimed technical solution.

The disadvantages of this invention are:

- the visher has an external thread attached to the ramrod (for example, the AK74M ramrod has an external thread);

- the need to use an adapter [2, 5] for attaching the visher to the ramrod;

- the structural ring rims on the visher increase the friction force of the patch (rags of a certain size) in the bore, which leads to the need to strengthen the physical impact on the ramrod and, as a consequence, bend it and the visher and cause mechanical damage to the barrel, since the ramrod material is not included in weapon set - textolite;

- the visher is made for the caliber of the M4 assault rifle - 5.56 mm (for example, the AK74M assault rifle has a caliber of 5.45 mm);

- the size of the visher does not allow its placement in a pencil case with accessories for small arms.

Distinctive features of the proposed technical solution from visher are:

- the presence in the core of the internal thread - fastening to the ramrod of small arms of domestic production;

- the dimensions allow its placement in a pencil case with the remaining components;

- lack of need for an adapter;

- the hyperbolic node creates an even distribution of the cleaning element (rags or tow) when moving small arms in the barrel.

The technical result of the utility model is aimed at preserving the protective coating of the barrel bore without losing the ballistic properties of small arms throughout its life.

The technical result is achieved by the fact that without changing the dimensional characteristics of the rubbing included in the set of the pencil case for cleaning the bore of the small arms, having a rectangular slot at the end for threading tow or rags and used in the bore several times [1], replaced by a square tip for stringing rags or tow on it with their retention on a hyperbolic node in the barrel of a small arms for the purpose of uniform advancement in a single use and to avoid mechanical damage Sgiach damage to the protective layer.

Distinctive features are the change in the form of wiping associated with the replacement of a rectangular cut at its end with a square-shaped tip with a hyperbolic assembly with preservation of all dimensional characteristics, allowing the product to be used without compromising the development of standards with small arms and improving the quality of barrel bore service.

The device tool for cleaning the barrel of a small arms is shown in the figure.

A tool for cleaning the bore of a small arms barrel consists of a metal rod of different diameters in length 1, having a hole in the lower base with a thread of a certain length for screwing onto the ramrod, and in the upper one there is a square tip 3 for placing rags or tows on it, which is attached by stringing and when applied, forms a thickening on the hyperbolic node 2, which is more tightly attached to the walls of the inner surface of the bore, which allows the absorption of dirt, combustion products, and distribute a layer of gun grease along the bore.

The operation of the device is as follows.

In accordance with the guidelines for small arms [1], to remove carbon deposits in the barrel bore, it is necessary to assemble the accessories: screw a small barrel bore cleaning tool on the ramrod, put on a tip 3 a cleaning element (rag or tow) and moisten it with a removal agent soot, straightening it on a hyperbolic node 2, enter the assembled structure into the bore from the muzzle. With one hand, holding the weapon by the muzzle, and with the other smoothly, without bending the ramrod, advance it along the entire length of the barrel. A dirty element that has appeared on the chamber side is removed into the container placed under the weapon (each element is used only once). This procedure must be repeated several times, each time treating a new cleaning element with a cleaning compound until it leaves the barrel clean.
