Abstract: A self-actuating firearm comprising a frame, a breechblock, a barrel provided with a bore, a cylinder which is associated with the barrel and forms an internal chamber which is connected to the bore of the barrel, by means of a gas tap, and a piston which is at least partially accommodated in the chamber and can be actuated by the gases that arrive from the bore upon firing. The piston floats with respect to the cylinder and the frame and comprises a portion which is external to the cylinder and is adapted to act with an impulsive action on the breechblock in order to recock the firearm upon firing.

Abstract: A device for controlling the feeder system of pump-action shotguns having a breech-block which is operatively associated, by virtue of two braces, with a cocking rod (3) moving between two stroke limit positions of the breech-block, a closed position and an open position. The rod motion actuates the feeding of a cartridge from a tubular magazine (5) to a rising block when the breech-block reaches the open position and from the rising block into the firing chamber of the barrel (7) when the breech-block returns to the closed position. The device includes a limiter (9) for limiting the opening stroke of the breech-block and for selectively preventing the breech-block from reaching the open stroke limit position.

Abstract: A portable weapon having a monolithic housing and stock made of plastics and provided with a metal insert for strengthening the structure.

Abstract: Gas-operated automatic weapon, including a barrel having a cylindrical portion that is blended with a cartridge chamber which can be closed by a breech block, wherein it includes a gas take-off that is located proximate to the cartridge chamber and is suitable to draw a fraction of the gases generated by the cartridge to actuate a piston that is suitable to open the breech block for automatic reloading of the weapon.

Abstract: An interchangeable rib assembly for rifles includes engagement portions (207) adapted to cooperate with respective posts (205) provided on the barrel (203) of a rifle so as to detachably fix the rib to the barrel. The rib can be advantageously made of plastic, carbon fiber, or the like, and have different shapes, each shape being appropriate for the contingent requirements (hunting, target practice, et cetera).

Abstract: In a trigger mechanism for firearms, in particular of the adjustable type for target-shooting pistols, the actuator of the mechanism is constituted by an elastic element (29) which is pivoted to the hammer (23) in an upward position and is pivoted, in a downward position, to an element (39) which can slide on the body (5) of the firearm; by acting on the sliding element, the elastic element is inclined so as to vary the direction of the actuation force with respect to the lever arm formed by the fulcrum (25) of the hammer with the upper pivot (27) of the elastic element. The safety device disengages the trigger from the operation of the firing mechanism.

Abstract: A semiautomatic firearm including a recoil spring acting on the bolt for closing the breech after the ejection of the case. The repositioning device includes an auxiliary resilient member which cooperates with the recoil spring, so that although a low-rigidity spring suitable for weak cartridges is used, the weapon works correctly even when firing powerful cartridges. The device thus allows to use a wider range of cartridges and reduces the negative effects of recoil.

Abstract: Firing mechanism for firearms, including a hammer which is actuated by a spring and rotates about a pivot, defining a cocked position and a percussion position; the spring acts directly on the hammer on a surface point which defines a lever arm with the pivot of the hammer, so that the lever arm is variable as the hammer moves between the cocked and percussion positions.
