Abstract (en)
[origin: EP0255732A2] Machine gun comprising a barrel (6) firmly mounted in a housing (4) and a locking unit (50) guided so as to move in the housing, said unit being preloaded by a pressure spring (52) into its extreme forward position and movable into its extreme rear position by compressed gas. The locking unit (50) is designed with an L-shape having a locking arm (56) behind the barrel (6) and a compensation arm (54) located above the barrel. The force of the spring (52) in contact with the mass of the locking unit (50) is calculated so as to limit its return travel to a shorter distance and the free length of the compensation arm (54). The mass of the locking arm (56) and that of the compensation arm (54) are matched to one another so that the center of mass of the locking unit (50) is located in the region of the intersection line between the front face of the locking bar (56) and the lower face of the compensation arm (54).
