An automatic gun for firing telescoped cylindrical ammunition, the gun comprising a sleeve for supporting a barrel, a breech, and a rear box which are all rigidly connected together by beams, the gun including a chamber disposed between the breech and the barrel and mounted to swing by pivoting about an eccentric shaft, and further including means carried by the breech and the rear box to feed ammunition to the chamber.

A striker device for striking a firearm cartridge, the cartridge comprising a case provided with a cap and the firearm including a bolt having a front face that is normally intended to be pressed against the cartridge case, a striking pin guided to move in translation in the bolt and including a tip for striking the cap of the cartridge, means for displacing the striking pin between a cocked position in which the striking pin is retracted into the bolt and a firing position in which the tip of the striking pin projects from the front face of the bolt to strike the cap of the cartridge, means for taking up clearance between the front face of the bolt and the cartridge, said means comprising a part having the striking pin passing axially therethrough and itself displaceable in translation relative to the bolt to occupy a firing position in which its front end projects from the front face of the bolt and bears against the cartridge case, the extent to which the tip of the firing pin projects relative to the front end of the moving part in the firing position being defined in a manner that does not vary by the striking pin coming into abutment against the moving part, and abutment means being provided on the striking pin and on the moving part to displace the moving part into a retracted position inside the bolt when the striking pin is returned to its cocked position.

Striker device for a firearm

The invention relates to a safety device, for an automatic weapon with 'floating' firing, including a rotating drum (2) driven by an external motor for driving a breech with a reciprocating motion. The safety device includes locking devices (14) for the rotating of the drum in each cycle, and control devices for retracting the locking devices when the weapon recoils, the control devices being fitted to act on the locking devices for a predetermined recoil travel distance, independently of the weapon recoil starting position.
