摘要:
- The invention concerns a butt pad for the stock of an individual firearm held against the shoulder, such as a shotgun, a sporting firearm, a military firearm, whether smoothbore or rifled which is made up of an external sheath or housing (12) elastically variable in shape consequent to pressure applied externally, by an internal high viscosity element (13), hermetically enclosed in the external sheath (12) and used to absorb and dispel the recoil energy, and a semi-rigid base and support element (14), integral with the external sheath housing and having a device (15) for a removable anchorage of the butt pad to the stock.
摘要:
This is a gas-flow device for semiautomatic or automatic shotguns, which consists of a gas-flow cylinder, closed at the front part by a flange with gas discharge ports (17) around the ammunition magazine, opposite the cylinder, a circular valve (18) that moves axially for controlled opening and closing of the discharge ports. The valve is kept in the closed position by a pre-stressed spring (19) and it moves to the open position when the gas pressure in the expansion chamber increases beyond a set value.
摘要:
A method, as well as a firearm formed by the method, for coupling the barrels of rifles in the breech starting from at least one barrel and from a monoblock casing. The breech of each barrel has an end portion of predetermined shape and diameter; the casing has a through hole for each barrel and a striking surface of axial stop of the barrel. The barrel and the casing are coupled mechanically, fitting the end portion of the barrel in the respective hole of the casing; the barrel and the casing are joined by means of laser fusion in at least two zones at the opposite ends of the casing and of the end portion of each barrel.

Trigger mechanism coupling-and-releasing device coupling a trigger mechanism to and releasing it from the bascule of a gun, wherein
the elements of the trigger mechanism are premounted on a trigger guard (11) which can be attached in the lower part of the bascule, the trigger guard (11) has a baffle (13) which extends into the bascule, the baffle (13) having a hook (14) facing towards the rear and intended for acting with a shoulder (19') of a trigger guard bolt (19) which is mounted and longitudinally movable in the bascule between a forward coupling position in which the shoulder (19') engages the hook (14) of the baffle (13) on the trigger guard (11) and a backward position for releasing the trigger guard (11) in which the hook (14) is no longer engaged by the shoulder (19'), a sliding safety catch (15) has a catch part (15') for interfering with an element of the trigger mechanism for rendering the trigger mechanism safe, the sliding safety catch (15) being mounted slidably movable in the upper part of the bascule, an oscillating safety lever (22) is mounted in the bascule and shaped so as to interact with the sliding safety catch (15) and to define for this sliding safety caatch (15): a backward safety position, an intermediate firing position (A) and a forward release position (B), and a top lever (18) is rotating mounted on the top part of the bascule, which top lever (18) can be moved by rotation from a position for locking to a position for unlocking the barrels (16) of the gun which are pivotably attached to the front part of the bascule, said device comprising a mechansim (26,27,31) for the release of said trigger mechanism, which extends between the sliding safety catch (15), the top lever (18) and the trigger guard bolt (19), for moving the trigger guard bolt (19) into the backward position for releasing the trigger guard (11) with the trigger mechanism from the bascule, said mechanism being constructed such that the release of the trigger mechanism is brought about by consecutively moving the sliding safety catch (15) from the intermediate firing position (A) to the forward release position (B) and rotating the top lever (18) in the position for unlocking the barrels.
