A trigger arrangement for an automatic weapon with switch-over between continuous firing and single-shot modes includes a hammer, a breechblock, a latch, a pivotably mounted trigger, and a firing lever. In the single-shot mode, the firing lever engages the hammer and retains it in tension while the trigger is depressed. When the continuous firing mode is selected, the firing lever is moved to an inactive position and retained by an engaging element. The engaging element is preferably a slider which is controlled by a safety and firing cessation roller that is actuated by an operating lever.

A small arm having a barrel (11) with at least one transverse bore (14) and a detachable silencer (62) including an expansion chamber (58) communicating with the transverse bore, comprising selectively operable closure means (34) arranged in the path of the combustion gases between the interior of the barrel and the expansion chamber is characterized by an arrangement in which the closure means (34) is prevented from opening or remaining in the open position when the silencer (62) is not in place. Thus, any risk of injury to the shooter is excluded.

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).

The invention relates to a sound dampened automatic hand firearm provided with silencing means for the firing of projectiles at a muzzle velocity in the subsonic speed range. In order to reduce also the breechblock noise during shot release, in addition to the muzzle noise and the projectile boom, a locking lever (18) is provided for locking the closed breechblock during discharge of the weapon. Preferably, the locking lever (18) is pivotable about an axis (19) oriented transversely to the barrel axis (24) and is held out of engagement by a spring (20). Associated with the trigger system is a catch (15) which causes the locking lever (18) to be pivoted into the locking position as the trigger (6) is being pulled. The catch (15) is pivotably mounted on the trigger (6).
