The housing part has a sighting mechanism on its upper side. A barrel is mounted in the housing part and a breech block is disposed in the housing part, which travels rearward on firing and cooperates with a locking system mounted in the housing part. A closing spring surrounds the barrel and means are provided for connecting the closing spring to the breech block. A firing pin is reciprocally received within the breech block. Also provided is means for removably retaining the barrel, closing spring, breech block, connecting means, and locking system within the housing part. A releasable key means, which holds the housing part in the fixed operative position, has a release position to remove the housing part in a direction substantially transverse thereto. The barrel, closing spring, breech block, connecting means, and locking system are retained within the housing part in operative positions with respect to each other, and the housing part is held in fixed position with respect to the stock.
