FIELD: small arms. SUBSTANCE: at a shot the barrel is locked due to magnetic coupling of the breechblock with the body. This principle is realized in a device consisting of the barrel, body with a permanent magnet in its rear that has a hole in the middle to pass the breechblock tail piece. A small-sized breech frame having a long tail piece with the mainspring fitted onto it is placed in the body. The breechblock tail piece rear passes through the hole in the permanent magnet and terminates in a flat screen, which contacts with the magnet in the extreme front position. In such position of the breechblock magnetic coupling arises between the breech frame and barrel pin, as well as between the tail piece screen and body. Overcoming of magnetic coupling and mainspring is sufficient for a short-time stoppage of the breechblock at a shot. EFFECT: improved design. |
