Abstract: Gun stock with adjustable comb includes a stock body having an adjustable comb which comprises a cheek rest member associated to a supporting structure associated to the stock body; the supporting structure has a hollow guide body slidable along a pin associated to the stock body; the guide body is slidable with respect to the pin in contrast to an elastic member; the guide body is engaged by a drive means that has a button accessible from the outside of the stock body; the height of the comb with respect to the stock body is adjusted by acting on the button for the engagement and disengagement of the guide body with respect to the pin integral with the stock body.

Abstract: A portable weapon assembly comprising a receiver made in a single polymer body without any inner metallic structural element; said assembly having an inner cavity.

Abstract: A smooth-bore barrel assembly including a first segment that extends downstream of a powder chamber, a bore followed by a segment having an increased diameter, and a final choke constituted by a first final portion and by a second final portion; the barrel is characterized in that the first segment has a divergent-convergent configuration, constituted by a divergent portion and by a convergent portion, or a solely convergent or solely divergent configuration. Advantageously, the barrel assembly can be provided in a modular form and includes three basic components: a barrel body, an extension, an inner choke member and/or an outer choke member.

Abstract: A recoil damping device for portable firearms, including a damping means inserted in the casing; a movable insert is functionally associated with the damping means and slide along a direction that is substantially axial with respect to the casing; the damping means is constituted by a body formed by a cellular solid having a stochastic structure, such as a foam, or having a nonstochastic structure, such as a reticular structure, lattice, etc.

Abstract: A trigger unit including a support adapted to be mounted on a receiver of a firearm and supporting components of a trigger mechanism and a safety system; the trigger unit is modular; the support includes a plurality of seats adapted to accommodate one or more different functional components in various combinations.

Abstract: A gun stock has a hollow body having a cavity in which a seat is formed; the seat is adapted to receive an insert; the insert has a passage hole for the passage of a bar which has a first end fastened to the body of the gun and a second free end which is threaded and engages a locking nut; a fastener plate is arranged between the locking nut and the insert and has a calibrated hole through which the free end of the bar passes; the fastener plate is arrangeable in different positions with respect to the insert in order to change the inclination of the stock with respect to the line of sight of the gun. The stock has additional systems for adjusting the distance between the buttstock and the trigger, the height of the comb, the length of the trigger pull, and the shape of the grip.
