A barrel balancing device for collapsible firearms (20) wherein at least one barrel (9) which is rotatable about a fixed hinging point (7) arranged on a action body (6), wherein an open-close top lever (13) is provided between a closed aligned position of the at least one barrel (9) and the action body (6), and a position disengaged and rotated upon opening of said at least one barrel (9) with respect to said action body (6), the at least one barrel (9) being carried by an iron fore-end (8), whe...

A break-action firearm with a breech housing, a barrel section that can pivot about a hinge bearing on the breech housing, and a removable fore-end, which contains on its front end a locking mechanism and on its rear end a bearing section for pivoting connection to the breech housing. This provides an easy-to-manufacture fore-end of the break-action firearm with minimal overall height, such that the hinge bearing grasps hinge pin, which project laterally inwards from the breech housing and which...

A shell cut-off latch for use in a break-open firearm having a magazine tube mounted parallel to the firearm barrel. The cut-off latch functions to retain cartridge(s) in the magazine tube when the firearm is in the break-open position and is cammed out of latching position when the firearm is in closed position and the action assembly and bolt means are in the forward, ready-to-fire position.

A pistol-type signal launcher having a spring-actuated hammer carrying the firing pin, a pivotally mounted barrel releasably retained in firing position by a plunger which is biased toward the barrel support cam by a spring which also biases the trigger toward cocked position, moving the sear into engagement with the hammer base; the hammer spring acts on the hammer through a rebound cam.

Articulated connection between the break-open action and the at least one barrel of a rifle with two coaxial pairs of articulation members, the two articulation members (1a and 2a) of each pair complementing each other, and respectively one articulation member being provided at the break-open action (1) and, respectively, at the corresponding sidewall of the barrel (20). These articulation members (1a and 2a) exhibit a coupling profile (P1 and P2, respectively) ensuring a shape-mating connection...

A firearm has a plurality of parallel barrels arranged uniformly circumfetially about a center axis. A hammer is translational from a cocked position to a fire position along said center axis. It has a firing pin offset from the center axis in correspondence to the spacing of the barrels from the center axis. The hammer is pivotal about said center axis during cocking to advance the firing pin from an aligned position in respect of one barrel to an aligned position in respect of a succeeding bar...

A hinge device for break-open type firearm comprises two pair of arcuate ridges on the breech slidably received in complementary grooves formed in parallel sidewalls of a receiver. One pair of ridges and complementary grooves is located forwardly of the hinge axis, with one ridge and its associated groove on each side of the ridge, and the other pair of the ridges and complementary grooves is located rearwardly of the hinge axis. In the closed position of the firearm, the ridges and grooves are ...

A barrel locking mechanism for a break-open-action gun having a barrel and a mechanical section rotatably engaged with each other by a hinge-pin. It has a lug secured to the barrel and having a delining surface. While a stationary receiver is integrally mounted on the mechanical section. On the top of it, a movable receiver having a delining surface corresponding to that of the lug is vertically movably mounted through a spring. When the gun is locked, the lug moves downwards depressing the mova...

A hold adjustment device between fore-end iron and action body in a break-open firearm comprising at least one barrel (13) mobile by rotation about a fixed hinging point (15) arranged on an action body (14) between an aligned closed position and a disengaged position rotated open with respect to the action body (14), a tenon (18) fixed at the bottom to the at least one barrel (13) for hooking with a fore-end iron (16), comprising a block (21), or cursor, axially mobile with respect to the fore-e...

A muzzle-loading firearm includes a breech plug for mating, non-threaded engagement with a housing located at the breech end of an axial bore of the firearm barrel. The plug includes a cylindrically-shaped body member having opposite first and second ends and an outer surface between the ends and configured so that when the plug is positioned within the housing, the outer surface is spaced close to the inside surface of the housing to facilitate insertion and removal of the plug from the housing...
