Abstract: The semiautomatic firearm comprises: a movable assembly (4) adapted to move against a return spring (10) by recovered energy resulting from pressure exerted when firing an ammunition (7), wherein the firearm comprises a stopper, a latch and a striker cooperating with a hammer (5) controlled by a trigger (6), at least one of a pivoting fork and a hammer used for locking the movable assembly in a compressed position of the return spring at a rear position of movement of the movable assembly, after each shot, an unlocking assembly (12) that is manually actionable and able to act on at least one of the pivoting fork and the hammer for releasing the movable assembly (4) and allowing the assisted return of the movable assembly (4) in order for reloading.

Abstract: A linear repeating firearm, with assisted ejection, including: a mechanism capable of recovering the energy resulting from pressure exerted when firing a round of ammunition by a gas operated system, to move a mobile assembly against return spring and including a stopper, a latch and a striker cooperating with a hammer controlled by a trigger. A locking mechanism is provided at the rear of the mobile assembly, to lock the mobile assembly in the compressed position of the return spring, after each shot. A manually actuatable unlocking assembly is capable of acting on the locking mechanism to release the mobile assembly and allow the assisted return of the assembly for reloading.

Abstract: An interchangeable trigger device comprising a standard trigger plate, allowing indifferently the mounting of a single selective trigger or of separate triggers. The plate comprises a flat base which can be fitted by pivoting into the opening of the receiver tang and a boss (1c) with a front lug (1d) to co-operate with the rear part of a double-acting sliding bolt (22), the front of which (22a) co-operates with the breech (23) when closing the gun; a top lever (14) actuating the sliding bolt (22) through an eccentric, for sliding it longitudinally according to three positions, a pivoting lever (24) with front stepped notches, and a double-acting elastic return means co-operating with the front nose of the bolt (22) for maintaining it in these positions.
