The invention relates to the automatic rifle weapon, namely to the design and scheme of operation of its mechanisms. The submachine gun includes a receiver (8), wherein it is placed a breechblock (12) with guide (1), a barrel (4), a gas tube (3), communicating with the barrel (4), and a magazine (20). The guide (1) of the breechblock (12) is made in the form of tube, in the fore-part of which it is fixed a gas screw (2), and the rear end is installed with the possibility of rotation onto an axle (7), rigidly fixed to the receiver (8). The axle (7) is joined with the guide (1) of the breechblock (12) by means of an opposing spring (9), placed into the tube of the guide (1). The breechblock (12) is equipped with a plate (14), and onto their surfaces there are made protrusions (15, 16), interacting with helical channels (17, 18), made onto the cylindrical surface of the guide (1).
