    • PURPOSE:To keep a high precision of getting a target by a method wherein an operation cam for operating a lock lever is engaged with the lock lever while a cannon returns from its rear seat position to its starting position, an engagement with the lock lever is released just before the bolt part closes the and the seat returning operation of the gun is set to be stabilized. CONSTITUTION:After closing a lock claw 8, a reverse hook 17 is abutted against a reverse hook operating cam and depressed downwardly and then a stopper for the reverse hook is released from a striker 15. The striker 15 moves forward under a resilient force of a striker spring 16, projects from a front end of a bolt part 4 to repel an ammunition W and then the cannon 3 and the bolt 4 are returned back to their seats under a reaction caused by launching of the bullet. A stopping projection 9 of a lock lever passes through an operating cam 12 while the barrel 3 moves back to its seat, thereby a front part of the lock lever 7 is moved inwardly and the lock claw 8 of the lock lever is released. With such an arrangement as above, the connected state between the barrel 3 and the bolt part 4 is released. Accordingly, the seat returning operation of the barrel 3 can be stabilized and a high precision of getting a target can be maintained.
