BREECH LOCK, ESPECIALLY FOR HAND FIREARMS

摘要

A bayonet-connector-like breech lock has a breech housing (1) and a breech block (8) with at least two radially projecting locking components (4). The enlarged region needed to rotate the locking components (4) takes the form of an annular space (5) wherein a locking sleeve (10) is fitted to rotate between an open and a locked end position. The locking sleeve (10) has a widened section (11) per locking component (4) which is aligned with the widened part (9) of the breech block drilling (2) in the open end position. The annular space (5) is completely filled by the locking sleeve (10) and the pushed-in breech block (8).
