The invention relates to automatic firearms and can be used to improve its operational properties - increase the safety of handling weapons. Known automatic weapons, such as a 12.7 mm machine gun "Rock", containing the receiver box with cap and barrel, bolt carrier with the bolt and with udarnikom mechanism (earring, head and other parts of the weapon (see 12.7 - mm TANK GUN "Cliff". TECHNICAL DESCRIPTION AND OPERATING INSTRUCTIONS. The order of the red banner MILITARY PUBLISHING house of the MINISTRY of defense of the USSR, Moscow, 1975, p.5-7, 15). A disadvantage of the known devices of automatic small arms is the lack of security in the handling of weapons associated with the possibility of unintentional shot when assembling weapons if the trunk cartridge. The objective of the invention is to improve the security of weapons in handling it. The technical result obtained by carrying out the invention, is the elimination of the possibility of a shot from the weapon when its fully assembled position. This technical result is achieved in that in the automatic small arms, containing the receiver box with the barrel, a movable system with udarnikom mechanism, sboros the first element, what is new is that the weapon has a spring-loaded stop moving system with the possibility of the elastic interaction with the Assembly element in its assembled position, and a movable hook system is made of emphasis. Run on spring-loaded arms stop moving system provides the ability to limit the stroke of the moving system in the front position to prevent firing udarnikom mechanism of the percussion cap of a cartridge located in the trunk. The provision of the elastic interaction of focus with Assembly element when closed provides the ability to shift focus that enables the mobile system to make a full stroke when the roll for the production of fire. Running on a movable hook system provides the possibility of mutual holding the stop and the moving system after the closure of the Assembly element that does not allow the gathering of mobile systems with emphasis and accidentally shot (to release the lock must cocked mobile system). Technical solutions with the features distinguishing the claimed solution to the prototype, is not known and obvious manner from the prior art do not follow. It can be considered that the claimed technical solution has a "novelty" and "inventive step". The invention is illustrated in the drawing, which shows a schema is automatic small arms. The device comprises a receiver box 1, a barrel 2, the Assembly element 3 with the spring 4, a movable system with 5 udarnikom mechanism 6. Assembly element 3 may be made in the form of a cover, folding butt, shop, etc. On weapons, for example, on the receiver 1, is installed on the axis of the stop 7, a spring 8, and the moving frame 5 is made hook 9. In the barrel 2 weapons may be the cartridge 10. The device operates as follows. When assembling weapons can be violated safety rules and in the trunk there is a cartridge 10. To ensure collection, after you install the receiver box 1 of the moving system 5, its advance in the direction of the barrel 2. When does not the moving system 5 to the front position of the focus 7 interacts with it, stop it, that does not allow actions udarnikov mechanism 6 on the cap of the cartridge 10, thereby eliminating the shot. During the further Assembly can be closed Assembly element 3. This spring 4 acting on the stop 7 and overcoming the action of the spring 8 tends to move the stop 7, however, this is prevented by the hook 9, which prevents the descent of the moving system 5 with the stop 7 and thus prevents the weapon from unintentional gunshot. In the future when cocking the moving system 5 hook 9 releases the stop 7, which under the action of the spring 4 moves and does not preclude d is Iranian moving system 5 when the loading of the weapon and firing. The work of the other mechanisms weapons are not described because of its being well-known and can be considered on the example of the prototype. The automatic small arms allows you to increase the security of firearms, including violation of the rules of operation. The device tested on prototypes of large-caliber guns, "KORD" produced by JSC "Zavod im. Vagetarian". Automatic small arms, containing the receiver box with the barrel, a movable system with udarnikom mechanism Assembly element, characterized in that the weapon has a spring-loaded stop moving system with the possibility of the elastic interaction with the Assembly element in its assembled position, and a movable hook system is made of emphasis.
