Description

The utility model relates to firearms and can find application in the design of effective muzzle devices for firearms, primarily small arms, intended to reduce undesirable phenomena associated with excess energy of powder gas and to reduce the unmasking factors of a shot.

A firearm attachment known from the prior art is patent US 10274278 (B2) dated 30.04.2019, which functions as a flash suppressor, a muzzle brake and/or for mounting, for example, a sound suppressor on a firearm. In one example, a firearm attachment includes a base adapted to connect to the muzzle end of a firearm barrel. The firearm attachment includes a plurality of longitudinal teeth that extend forward from the base. The base includes a plurality of openings located behind the teeth and that extend from a channel inside the base through the outer circumference of the firearm attachment. The openings have a first diameter in the channel and a second larger diameter on the outer circumference. The openings are adapted to impart thrust to the firearm attachment in response to combustion gases passing from the channel through the openings to compensate for the rise of the muzzle associated with the firearm.

A muzzle flash suppressor is also known according to patent CN 208671785 (U) dated 03/29/2019, which relates to a multifunctional fork-type muzzle flash suppressor, which includes a fork body, an installation part, a positioning ring and a tail interface. The fork body, the installation part, the positioning ring and the tail interface are formed as a single unit, and the central channel passes through the fitting part, the positioning ring and the tail interface; the fork body is located at the front end of the mating part, the positioning ring is located at the rear end of the mating part, the positioning ring is located at the rear end of the mating part. The flame suppressor is provided with an outer circle of the positioning ring, and the outer circle of the positioning ring is provided with a positioning protrusion and a relief groove. The tail interface is located at the rear end of the outer circle of the positioning ring. The utility model has a fork-shaped structure. The powder gas in the fork-shaped flame arrester first expands stably through the central channel, then continuously compresses and guides through a series of triple cylinders between the grooves, and then flows out through the central channel, slots and the front part. This can control the expansion and flow of gas, weaken the shock wave, and effectively reduce the intermediate and secondary flame.

The disadvantages of known designs include the unreliability of the units that ensure the modularity of the design.

The objective of the declared solution is to eliminate the shortcomings of analogues, as well as to create a universal muzzle device that reduces recoil and barrel rise during firing, reduces flash from combustion of powder gases, and ensures modularity of the design due to the possibility of installing additional muzzle devices.

The technical result is to ensure the modularity of the design.

The technical result is achieved due to the fact that the muzzle device includes a body containing a central channel, a tail section, a middle section and a fastening section, wherein the tail section of the body is made in the form of three petals; a seat diameter and a seat cone, as well as an end ledge behind the conical section; the fastening section contains a thread, and a groove is made along one of the petals of the tail section.

This useful product is used on civilian and military small arms. The design of the muzzle device is explained by drawings Fig. 1-3, where:

1 – petals;

2 – hole;

3 – groove;

4 – groove along the petal;

5 – landing diameter;

6 – landing cone;

7 – end ledge behind the conical part;

8, 9 – thread;

10 – offset thread.

The three-petal (1) design feature (Fig. 1) allows one of the main problems during shooting to be solved, namely the formation of a flash from combustible powder gases. The design also includes a hole (2) and a groove (3), which reduce the barrel rise during firing.

The principle of the connection is that the groove (4), made along one of the petals, serves to guide the mating part (rail) of the additionally installed muzzle device in the required position and to prevent rotation around the axis of the declared muzzle device.

The diameter of 23 mm (5) when connecting the mating part of the additionally installed muzzle device sets the coincidence of the axes of the two products, and the cone of 160.2 degrees (5) fixes this alignment, which in turn ensures the reliability of the structure as a whole and eliminates the angular deviation of the axes between themselves under a perpendicular load on the product.

Axial closure on the muzzle device will be provided by means of an end ledge behind the conical part (7), which is provided in advance in the project for fastening other products to the declared muzzle device. This solves the problem of the principle of modular design, which in the future will allow for the development of parts and units mated using this design element.

The general design has barrel mounting options depending on the interface used by the weapon manufacturer, and can be made with M24*1.5 mm (8), M14*1L (9), etc. threads. For M14*1L threads, there is the possibility of additional fixation of the product with an M5 clamping screw; for this purpose, an offset thread (10) is provided in a plane perpendicular to the axis, which provides additional clamping of the axial barrel thread.

Thus, the implementation of the entire set of design features of the declared solution allows us to achieve:

- reducing the time it takes to aim for the next shot;

- increasing the accuracy of weapons in general;

- decrease in average point of impact;

- reduction of the shooter’s physical strength and concentration expended during shooting and, as a consequence, reduction of fatigue;

- the ability to use additional muzzle devices due to the modular interface.

This product can be manufactured using metalworking machines of the milling and turning group.
