Abstract
Firearms with cartridge-case ejection, including a barrel with a movable bolt carrier with a bolt, with a breech face, with a movable ejector and with a firearm-fixed functional edge which pushes the ejector into its ejection position when the bolt carrier moves back after a shot has been fired. In order to create an ejection that is always evenly performed, an ejector lever is arranged on the bolt carrier so that it can be rotated about a pivot axis running normal to the firearm's central plane, which abuts against the functional edge when the bolt carrier moves backwards and thereby twisted so that it abuts an impact surface of the ejector and forces it to the eject position.
