Abstract

The invention relates to an automatic shoulder arm, such as a machine gun, which can be changed over to semi-automatic fire, burst and automatic fire. In order to reduce the ammunition consumption in the automatic fire mode and to increase the hit rate, the weapon is provided with a mechanism regulating the cyclic rate of fire (27, 21 to 25) which reduces the cyclic rate of fire in the automatic fire position by means of a deceleration member (27) releasing the next shot. A hammer (14) acting upon a firing pin (10) when a shot is released is preferably releasable by deceleration member (27), which hammer is provided with an additional detent (24) being effective in the automatic fire position and disengageable by deceleration member (27) via a deceleration release lever (21). (FIG. 2a).
