Abstract: A firearm with an automatic cycle, includes a frame (1), a barrel (2) mounted on this frame (1) and at least one breech bolt (3) mounted in a movable manner in relation to the frame, whereby the barrel (2) and the breech bolt (3) can be separated so as to make it possible to feed ammunition. The barrel (2) is also movable in relation to the frame (1), both forward and backward relative to a rest position, whereby the barrel (2) and the breech bolt (3) are mounted such that the barrel (2) can recoil together with the breech bolt (3) relative the rest position and can continue, when returning forward, can continue beyond the rest position and then return to the rest position, whereby the advancing of the barrel (2) beyond or forward of the rest position takes place at least partly after the separation of the barrel (2) and the breech bolt (3).

Abstract: Ejection device for a firearm having an automatic or manual cycle, wherein the firearm includes a frame (1), a barrel (2) mounted on this frame (1) and which is equipped with a firing chamber (3) and movable elements (4) which can be moved backward in relation to the firearm (1) during recoil, and wherein the movable elements (4) include an extractor (9) for carrying along a casing (10) during recoil and an element (8) to close the chamber (3). The ejection device also contains an ejector (11) mounted in the closing element (8). The ejection device includes an ejection lever (16) mounted in a pivoting manner around a transverse axis (17) on the frame (1) at the back of the chamber (3), and including a guiding element (18) provided with a passage (19) for a casing (10). The ejection lever (16) tilts between a lower position whereat the entry of the its passage (19) is situated in the ejection trajectory of the case (10) as the movable elements (4) return forward and a higher position.

Abstract: Longitudinal magazine for individual weapons such as, submachine gun, rifle, machine-gun and similar, of a type that can be mounted on the upper part of the weapon and in the axis of the frame, characterized in that this magazine mainly consists in a first part (3) formed by a tube forming the magazine as such and in which the cartridges (5) are being stored with their longitudinal axis perpendicular to the longitudinal axis of the magazine (2); a second part (4) consisting in a transfer element (34) showing on both sides an oblong port respectively (32-46), mutually related with two skews (41-42) stretching over an angle of 90 degrees, one of these ports (32) constituting the connection between aforementioned parts (3) and (4) while the second port (46) constitutes the connection between aforementioned part (3) and the weapon (1) with which the magazine (2) cooperates; and in means (54) allowing for the transport of the cartridges (5) inside the magazine (2).
