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.

Abstract: A barrel assembly for firearms including one or more tubes associated with a mono-block, characterized in that the mono-block has one or more cylindrical protrusions which allow the connection of one or more of the tubes and the subsequent joining thereof by welding, adhesive bonding, forcing, etcetera. The method for manufacturing the barrel assembly is characterized in that it includes the steps of: providing a mono-block which includes one or more front cylindrical protrusions, one or more partial chambers axially aligned with the protrusions, and corresponding collars for the cartridge seats, extractor seats, and closure members such as closure tenons or other members; all the members are completed with their final dimensions; performing an overall heat treatment of the mono-block and of the barrels; connecting the tubes, which constitute the barrels of the firearm, by welding, adhesive bonding, forcing, etcetera, to the protrusions.

Abstract: A closure for break-action firearms which includes a barrel assembly which is hinged to a break-action assembly so as to form a closed position and an open position of the firearm; the barrel assembly has a breech end which is opposite with respect to a breech face of the break-action assembly when the firearm is in the closed position. The structure is characterized in that it includes a plate which is associated with the break-action assembly and is interposed between the breech end of the barrel assembly and the breech face of the break-action assembly in the closed position, in which the plate closes the breech end by virtue of a means for the temporary locking of the plate on the barrel assembly.

Abstract: A modular portable weapon has a supporting module, constituted by the barrel of the weapon, and modules which are mutually functionally independent and are associated with the supporting module. The modular weapon according to the invention allows the user to compose the weapon by choosing, for example, a type of barrel, stock and tubular magazine among the alternatives that are commercially available, with the characteristics best suited to his requirements.

Abstract: A locking and recocking assembly with swivel breech-lock and rotating locking head particularly designed for inertially-actuated weapons, which combines in a single assembly all the functions for locking, opening, case ejection and recocking with locking return, required for correct operation of the weapon; those functions were, until now assigned to various components variously assembled on the weapon. The locking and recocking assembly with swivel breech-lock and rotating locking head has the entire mass, required for inertial operation, concentrated in the swivel breech-lock, which is accommodated completely within the supporting structure of the weapon, such as the sheath or barrel extension or breech of the weapon. All this leads to better balancing and stability of the weapon, higher reliability in operation, greater constructive simplicity and ease of assembly and disassembly.

Abstract: A quick coupling for the stock of a portable weapon, automatically provides the stock with a specific drop and cast upon its coupling by means of an interchangeable plate which can be replaced easily. The characteristics and the number of plates available are such as to meet the variation requirements made by the various users. The new quick coupling has considerable advantages in terms of constructive technical simplicity, ease of drop and cast adjustment, quick disassembly and maintenance of the weapon.
