摘要

The system is applied in short-barrel self-loading weapons. It makes the structure lighter and attributes greater energy to the shot. The system includes a closed frame (5) with a front (4) and rear (8) stop. A canal is fabricated in the rear zone of frame (5). Retracting spring (3) of the weapon is fixed between the front stop (4) and stop (6) of the weapon body. Breech-block (9) is fitted behind the barrel (1) and near the rear stop (8) and has a pushing rack (10) positioned in canal (7) having a stopping threshold (11). An arm (13) is positioned in seat (12) machined in the body (2) of the weapon under the stopping threshold (11). The closed frame (5), by a lever (14) is in contact with the arm (13) and the rear stop (8) envelops the rear wall of the breech-block.
