Abstract: A hammer assembly of the automatic mechanism of a firearm, comprising a breech (4) that is pushed towards the barrel (3) by a return spring (6). On the breech (4) and/or in the breech case (3) a hammer carrier (10) is arranged in a sliding way that is pushed towards the breech by a striking spring (13). The hammer carrier (10) carries a hammer (11). The hammer (11) is arranged on the hammer carrier (10) movably between the front end position and the rear end position wherein between the front and rear end positions of the hammer (11), there is a play (F). The hammer (11) is pushed to the front end position by the hammer spring (12).

Abstract: An automatic action assembly of a firearm, comprising a barrel (2) with a sliding cartridge chamber (1) arranged in a sliding way between the front and rear dead center. The movement of the sliding chamber (1) is delimited by at least one first stop (3) on the sliding chamber (1) and a corresponding at least one second stop (4) connected to the barrel (2). Between the first stop (3) and second stop (4), there is a play (A). In the rear part of the sliding chamber (1), a breech block (5) is lockably connected at the end of which a breech block (5) carrier (6) is to mounted in a sliding way. The breech block (5) carrier (6) is pushed by a return spring (7) towards the barrel (2). The breech block (5) is fitted with an unlocking mechanism for delayed disconnection of the breech block (5) from the sliding chamber (1).

Abstract: The firearm comprises a firearm housing (1) connected to the barrel assembly (2), a firearm breech (3) mounted in the housing (1) and connected to a spring for forcing the breech (3) to its initial shooting position, a tensioning lever (11), a tensioning lever (11) carrier (4) that is connected to the tensioning lever (11) and arranged for common linear movement in the axial direction of the firearm with the tensioning lever (11) in and against the shooting direction. The tensioning lever (11) contains the first latch (6) and lever part (7) wherein the first latch (6) is arranged for controlled movement by means of manual control of the lever part (7) from the first position—shooting position, wherein the first latch (6) is engaged with the barrel assembly (2), fixing the tensioning lever (11) to the barrel assembly (2), to the second position, wherein this engagement is disconnected and the tensioning lever (11) can move in the said axial direction against the shooting direction.

Abstract: An ammunition magazine for firearms for multiple types of cartridges with different calibers comprises a magazine body where a cartridge feeder fitted with a spring is movably arranged, while at least two pairs of opposite guide ribs are arranged on the inner wall of the magazine, namely rear guide ribs and central guide ribs. In the magazine body, on the inner wall of the magazine, at least one pair of opposite front guide ribs is arranged in front of the rear guide ribs and the central guide ribs, with the height of the front guide ribs being bigger than that of the rear guide ribs and of the central guide ribs.

Abstract: A connection mechanism for connection of a firearm receiver and a shoulder mount, the fire arm receiver comprising a closing part, the closing part containing a latch arranged in a movable way between a locking position, in which in an assembled firearm the latch engages with the receiver and the closing part is prevented from being removed from the receiver, and an unlocking position, in which the latch disengages from the receiver and the closing part can be removed from the receiver. The closing part further contains a lever to control the movement of the latch from the locking position to the unlocking position and/or from the unlocking position to the locking position.
