ABSTRACT:
An automatic firearm has a recoiling bolt connected by an amplifying lever to an additional mass subjected to the action of a recoil spring. One arm of the lever, via a push member, holds in a position of rest a stop pawl which is capable, when it is in active position, of retaining a striking hammer in striking position. The breaking of the lever permits the movement into the active position.
