AUTOMATIC SUBMACHINE GUN FOR EXPLOITING RECOIL COMPRISING TWO OPPOSING LEVERS FOR THE HAMMER, ONE ASSOCIATED WITH SINGLE-SHOT FIRING MODE AND THE OTHER WITH BURST FIRING MODE

摘要

An automatic submachine gun for exploiting recoil, comprises: a stock (2); a fixed barrel (4); a grip (3) provided with an extractable butt (20); a bolt (6) sliding in direction parallel to the longitudinal axis of the barrel (4) inside the stock (2) for locking the breech of the barrel (4); a device for recovering the recoil kinetic energy of the bolt (6); a hammer (22) swinging in opposition and through the action of a spring actuator element (23) between a cocked position and an uncocked position; a trigger assembly for the hammer (22) comprising in turn a swinging trigger (21) pivoted on the stock (2) and operatively connected to a sear lever (26), an opposing lever (28) of the hammer (22) for single shot fire actuatable by the sear lever (26), and an opposing lever (29) of the hammer (22) for continuous burst fire actuatable by the sear lever (26); a manual fire mode selector (34) connected to a rotating shaft (35) having a cam means (36) interacting with said opposing lever of the hammer for single shot fire (28) and with said opposing lever of the hammer for burst fire (29); an extractable magazine (8) for loading cartridge ammunition in a cartridge chamber of the barrel (4); a firing pin (37) for the ammunition actuatable by the hammer (22) and sliding in a direction parallel to the longitudinal axis of the barrel (4) in a seat provided in the bolt (6); the hammer (22) being configured and disposed so as to interact with the bolt in such a way as to absorb a significant fraction of the recoil kinetic energy of the bolt (6) for the attainment of the cocked position.
