Abstract
A weapon includes a barrel having a barrel axis and a breech-side end having an end face; a breech ring affixed to the breech-side end; and a catching and ejecting device movable parallel to the barrel axis for immobilizing a rimless cartridge case in and extracting the cartridge case from the barrel. The catching and ejecting device has a pivotally supported ejector; an extractor claw mounted at an end of the ejector and arranged for engaging into an ejector groove of the cartridge case; a spring biasing the ejector for urging the extractor claw generally radially inwardly; and a guide member mounted on an end of the ejector for contacting the cartridge case during cartridge feed into the barrel whereby the ejector and the extractor claw are pivoted against a force of the spring for maintaining the extractor claw out of contact with the cartridge case. The extractor claw is moved by the force of the spring into the ejector groove of the cartridge case as the guide member runs off and remains behind the cartridge case during cartridge feed. A locking pocket is provided in the end face of the barrel end for receiving a portion of the extractor claw upon completion of the cartridge feed and while the extractor claw engages into the ejector groove of the cartridge case.
