Description

The invention relates to firearms and can be used in systems with a removable magazine.

Known firearms (see patent RU N 2211431, publ. 08/27/2003, bull. No. 24), taken as a prototype. The device includes a receiver, a magazine and a trigger guard.

The disadvantages of this device are:

- low reliability of the trigger mechanism due to the fact that the loads arising from the supply of cartridges from the magazine are transferred to the trigger housing, causing increased wear on the seats and making it impossible to fine-tune the trigger mechanism;

- the complexity of debugging placed on one removable base of the trigger mechanism and seats for the store.

The proposed invention solves the problem: improving the operational characteristics of weapons.

The technical result obtained by carrying out the invention consists in protecting the trigger from external influences, simplifying the individual adjustment of the trigger and caring for it.

The specified technical result is achieved by the fact that in firearms, including a receiver, magazine and trigger guard, it is new that it is equipped with cracked protrusions and grooves made in the magazine, and the hook guard is made with the possibility of longitudinal movement and ensuring the interaction of cracked protrusions with grooves for fixing the store on the receiver.

The execution of the fencing of the hook with the possibility of longitudinal movement and ensuring the interaction of the rim tabs with the grooves for fixing the store on the receiver allows for the rapid replacement of the store and fix the store.

Technical solutions with features distinguishing the claimed solution from the prototype are not known and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

The invention is illustrated by drawings, where in Fig.1 shows a device for fixing the store in position for shooting, Fig.2 - device for fixing the store in position for replacing the store.

The device for fixing the store includes a trigger guard 1, having guides 2, on which are made crackers 3.

The device operates as follows. The store 4 of a traditional design is located in the receiver 5 of the weapon so that the front of the trigger guard 1 is under the store (in the fighting position). The magazine 4 is held in the receiver 5 by means of cracking tabs 3 on the guides 2 of the trigger guard 1. The guides allow the trigger guard of the trigger 1 to move relative to the receiver 5 in the longitudinal direction. In the front position, the trigger guard 1 is held by the latch 6 of the receiver 5. To replace the magazine, by pressing the latch 6, push the trigger guard 1 to its extreme rear position (contact with the trigger 7 should be excluded). At the same time, the cracked protrusions 3 of the guides 2 of the trigger guard 1 exit from the corresponding grooves of the magazine, which is pulled down. Then the equipped magazine 4 is inserted, after which the guard of the trigger 1 is moved forward until the latch 6 is activated.

Claims (1)

Firearms, including a receiver, a magazine and a trigger guard, characterized in that it is provided with cracked protrusions and grooves made on the magazine, and the hook fence is made with the possibility of longitudinal movement and the interaction of the nut ledges with grooves for fixing the magazine on the receiver.
