Abstract
A hand-held automatic firearm comprises a breechblock, which is longitudinally slidably guided and at its forward end has a standing face for engaging a cartridge, a hammer, which is adapted to be cocked by the breechblock as it recoils, a sustained-fire lever, which is controlled by the breechblock and catches the hammer as the breechblock advances, and an ejector, which is movable relative to the breechblock and ejects the cartridge case as the breechblock recoils. In order to provide a compact and inexpensive design, the sustained-fire lever comprises a follower arm, which protrudes toward the barrel and extends into a track groove, which is formed in the breechblock and opens into the standing face, and the follower arm has a free end, which acts as an ejector.
