Abstract

This utility model refers to small arms and can be used as an individual weapon of a soldier. The technical result is that the slide with sliding stops, actuated by rods according to the "umbrella" principle, is highly reliable, simple in design, and quick in locking the barrel , the action of powder gases is minimized, since the lugs are located farther from the breech cut of the barrel. The bolt carrier has a rigidly fixed striker with its lower part. The absence of trigger and part of the bolt carrier leads to a decrease in the weight of the machine and minimizes delays during firing.This machine, based on locking the barrel by expanding the lugs, consists of a barrel, a receiver, a gas tube with a receiver pad, a stock, a magazine, a trigger mechanism, a gas piston with a bolt carrier and a bolt with lugs, in which the lugs abut against the seal inside the receiver, the lugs do not go beyond the weapon and serve to lock the bore. Essence: the shooter takes the bolt carrier to the rear position, and it gets up to a combat platoon. The bolt carrier is rigidly coupled to the striker, which is located inside the bolt. Also, the bolt as a frame is fastened with the bolt lugs with the help of rods. When the trigger is pressed, the bolt carrier with the bolt breaks down from the combat platoon. The lug catches the sleeve flange from the magazine and sends the cartridge into the chamber. After the bolt rests against the barrel, the bolt carrier continues to move forward, spreads the lugs for the protrusions in the receiver. At the moment of locking, the rigidly fastened striker punctures the igniter capsule and a shot occurs. Powder gases take the bolt carrier back and the process starts again. Thus, the proposed machine with lugs will significantly increase the combat capabilities of the soldier. Easy to design and use.

Description

This useful model relates to small arms and can be used as a standard soldier's weapon, designed to destroy enemy manpower and fire weapons.

Currently, there are many types of small arms that are in service with motorized rifle units and special forces. The main sample is the AK74M and its modifications. According to several indicators, AK74M is inferior to foreign counterparts in fire efficiency:

1. Large spread of bullets when firing bursts;

2. The shutter is rotated 90 degrees, which increases the time for locking the barrel;

3. The number of shots is 2 pcs., Which reduces the stability when fired;

4. Combat protrusions develop their resource due to the impact on them of powder gases;

5. The firing mechanism is presented in the form of a complex device consisting of springs and cam mechanisms;

6. Escorting the bolt carrier by an inexperienced shooter in the production of the first shot, leads to a delay in firing or breakdown;

7. Lack of further prospects for the development of effective application.

Modern local conflicts, rapidly changing tactics of close combat, have shown the need to create a newer individual soldier's weapon, which will have a more effective impact on the target, compared to foreign counterparts. Thus, the aforementioned determines the relevance of the development of this utility model. To solve this problem, I propose a useful model "Automatic machine with lugs", which includes a new bolt with lugs, in which the lugs abut against the seal inside the receiver, the lugs do not go beyond the weapon and serve to lock the barrel, which will allow to increase its combat capabilities in modern close combat conditions.

The purpose of the utility model is to increase the effective fire impact on the target with the soldier's standard weapon.

The advantages of this utility model shown in FIG. 1 is:

1. Simplicity of construction;

2. Lack of development of combat stops;

3. Easy to use as directed by an inexperienced soldier;

4. Improved accuracy when firing bursts.

The main difference of this utility model from the previous ones is that a new automation scheme is used, based on the spreading of combat stops according to the "umbrella" principle.

Operating principle:

The shooter moves the bolt carrier to the rear position, and it gets into a combat platoon, i.e. it does not return back to the breech. The bolt carrier 3 is rigidly coupled to the striker 9, which is located inside the bolt. Also, the bolt carrier 3 with the help of rods is fastened to the lugs of the bolt 2. When the trigger is pressed, the bolt carrier 3 with the bolt 5 breaks down from the combat platoon. Lug 7 catches the flange of the cartridge case from the magazine and sends the cartridge into the chamber. After the bolt 5 rests against the barrel 1, the bolt carrier 3 continues to move forward, spreads the lugs 2 for the protrusions in the receiver 4. Thus, the barrel bore is locked. At the moment of locking, the rigidly fastened striker 9 pricks the primer-igniter and a shot occurs. Powder gases take the bolt carrier 3 back, and with it the bolt 5. When moving back, the sleeve rests on the reflector, which passes along the groove 6. Coming out of engagement with the ejector 8, it is extracted outside. And the process happens again.
