摘要： Automatically feeding firearm having a bolt (2) which upon shooting is reciprocally moving in the receiver (1) of the weapon actuated by a recoil spring (4), and in which the bolt (2) when being set for firing its first shot, for the purpose of executing its function, is pulled back and is kept tensioned in the receiver until a trigger bar or a similar lock means releases the bolt, or alternatively the bolt is directly returned to a front position after having brought a cartridge from the magazine into a cartridge position and after having tensioned a separate firing mechanism, and in which the weapon is formed with an actuation bar (5) projecting from the back (9) of the weapon and adapted for tensioning the bolt (2) by being pulled rearwardly, which bar after said tensioning of the bolt is adapted to be returned to its initial front position. The actuation bar can be a separate actuation bar or preferably a recoil spring bar (5) which is received in a groove (3) of the bolt (2), and about which the recoil spring (4) is guided.
