Bolt assembly with locking system
摘要:
A locking system for firearms including a locking ring rotatably mounted to a bolt. As the bolt is moved through a bolt slide, the locking ring engages a cam member, which causes the locking ring to rotate about the bolt, which can remain fixed against rotation.
