Gun e.g. machine gun, has safety mechanism that cooperates with tube locking unit, such that safety mechanism acquires its release position only by removable tube that is locked at tube locking unit

摘要

The gun has a removable tube (4), a tube locking unit (22) to lock the removable tube in the gun. A safety mechanism prevents firing of the gun during off state of the mechanism and enables firing of the gun during release state of the mechanism. The safety mechanism cooperates with the tube locking unit in such a manner that the safety mechanism acquires its release position only by the removable tube that is locked at the tube locking unit.
