Abstract: Firearm comprising a receiver (2); a barrel (6) mounted with one end on the receiver (2); a breech (8) equipped with a loading lever (9) mounted, in a way so that it can slide, in the receiver (2); at least one return spring (15) to return the breech (8) to its closed position, characterized in that the return spring (15) is a tension spring of the ‘constant-force’ type that is mounted between the breech (8) and a fixed support (12) with respect to the receiver and the barrel.

Abstract: Improved gun with automatic loading of cartridges, comprising a cartridge loader in the form of a tubular magazine (4), characterized in that: The magazine bottom (18) is mounted in a way so that it can slide in the axial direction (X-X?) with respect to the tubular magazine (4). The sliding magazine bottom (18) is equipped with a shock absorber (26) able to absorb the shocks exerted on the magazine bottom (18) in the axial direction (X-X?) of the tubular magazine (4). The cartridge follower assembly (19) provided with a shock absorber (29) that can absorb the shocks exerted on the follower assembly (19) in the axial direction (19) of the tubular magazine (4).

Abstract: Production method for a monobloc rifle receiver of aluminium or aluminium alloy, characterised in that this method consists of the realisation of individual parts of the receiver, which, in an assembled state can form a receiver; followed by any mechanical adjustments; followed by the assembly of these parts (8) by welding.

Abstract: Butt with recoil pad for a shoulder-held firearm, with the butt comprising a recoil pad, characterized in that the recoil pad is mounted on the butt by means enabling the position of the recoil pad to be adjusted with respect to the butt so as to be able to personalize the position of the recoil pad for the shooter with respect to an average position in which the recoil pad is primarily located in the extension of the butt.

Abstract: Exchangeable choke for a fire arm with a smooth gun barrel, whereby said choke is provided with mechanical coupling means to mount and dismount the choke, characterized in that the choke is equipped with additional sealing means so as to seal the choke, at least in one place, in relation to the gun barrel, as well as to prevent the choke from being unscrewed during the shooting.

Abstract: A semi-automatic rifle includes a frame (2); a barrel (3); a sliding guide (9) mounted in the frame (2) and forming one piece with breech bolts (10) which make it possible to control the recocking and the locking of the rifle (1); an automatic recock device (12) includes a piston (13) mounted in a gas cylinder (14) whose chamber (15) is connected to the bore (7) of the barrel (3) via a vent hole (16), whereby the piston (13) makes contact with the head of a sliding guide (17) which is connected to the sliding guide (9) and which is mounted in a sliding manner on a guiding rod (19) which forms one piece with the frame (2) and which is mainly parallel to the axis of the barrel (3).

Abstract: A firing mechanism for fire arms comprising a casing (1) and a trigger guard (1′), a barrel (3), a mobile bolt (5) in the casing (1), comprises a hammer (7) controlling a striker (10), a spring (9) pushing the hammer (7) in its tumbled position, a tumbler (11), a trigger (14) controlling the tumbler (11) by means of a separator (15), a bolt stop (19) which stops the backward movement of the bolt (5) in a locked position and makes the bolt (5) assume another position, a control lever (20) which co-operates with the bolt stop (19) which is also mounted in a revolving manner in the trigger guard (1′).
