FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of armament, namely the automation of small arms. Automation of small arms includes a frame of arms with the focus of the return spring and the emphasis of the short stroke of the trunk with the receiver, trunk with a receiver, bolt with a shutter frame, return spring. Claimed automation with a short stroke of the barrel with the receiver is designed in such a way that, at the time of the shot, the trunk, with the receiver, the bolt and the shutter frame, move together until the stop is touched by the stop of the short stroke arm on the weapon frame, then the shutter frame moves by inertia, turning the bolt, and when the shutter's warheads come out from behind the trunks of the receiver, ensuring that the bolt is unlocked, the bolt and the bolt frame move together, compressing the return spring. When rolling back, the return spring moves the bolt frame with the bolt to the breech part of the barrel, the bolt stops, the shutter frame continues to move, turning the bolt, while the shutter's warheads are installed behind the trunks of the trunk with the receiver.

EFFECT: it is possible to maintain the reliability of automation with simplifying the design, reducing the number of parts.
