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 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 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 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.

Abstract: A balancing device for firearms having at least one barrel and one stock, a front support and a rear support respectively mounted in a region adjacent to the muzzle and in the region of the stock of the firearm; the front support and the rear support are configured to support one or more weight members which are modular and mutually analogous.

Abstract: A portable firearm with quick coupling removable stock comprising a firearm body, provided with a grip, and a removable stock, which can be associated with the firearm body by means of a quick coupling device; the quick coupling device includes a hollow body, which is fixed to the firearm body, and an elongated body, which is integral with the stock and can be at least partially inserted in the hollow body; the device includes an interference member adapted to lock the elongated body in the hollow body in a locking position; the interference member is movable from the locking position to a release position in which the elongated body is movable and can be extracted from the hollow body. The interference member can be actuated easily by using a component of the firearm itself as a tool.

Abstract: A gun stock with interchangeable cheek rest, including a main body and a cheek rest removably associated with the body and including a supporting structure and a cheek pad that rests on an elastic member associated with the structure; the elastic member is constituted by a leaf spring that is associated with the structure and is easily interchangeable. The cheek rest is applied to the stock body by means of a quick coupling, with or without the use of tools.

Abstract: An interchangeable trigger assembly for firearms, particularly for over/under shotguns, which can be applied within a break action of a gun, by insertion in a lower opening of the break action; the assembly includes two detachable portions: a firing unit and a trigger unit, the firing unit including firing members; the trigger unit including at least one trigger which acts on actuation members of the firing members.

Abstract: A bolt assembly with improved rotating locking head, comprising a rotating locking head associated with a bolt body and movable with respect to the bolt body with a combined rotary and translational motion; the rotating locking head having at least two working positions: a closed position, wherein the rotating head closes the breech of the firearm, and an open position, wherein the rotating head is at a distance from the breech; the bolt assembly has an auxiliary pusher that biases the rotating head from the open position to the closed position.

Abstract: A recoil damping device for portable firearms, including a casing in which a recoil damping means is inserted; the damping means includes a fixed part, which is integral with the casing, and a movable part able to slide along a substantially axial direction inside the casing; the damping means is made of a material having a certain elastic hysteresis and includes a set of flexible members connecting the fixed part to the movable part; the flexible members have different stiffnesses.
