Bundstykke til et repetergevær samt låseramme til et sådant bundstykke

摘要

The device has a bolt chamber arranged in a lock guide, and a locking sleeve arranged concentric to the chamber. Locking elements are moved by an expansion device between inner and outer locked positions. A locking lever (27) is activated by a chamber stem (29) associated with cam element (41a) that rotates in the guide with a rear contact surface for support against a fixed control element (47). Another cam element (41b) is rotated independently of the former cam element and includes a rear control cam (48) for support against the control element associated with the locking lever. An independent claim is also included for a receiver, comprising side guide grooves.
