Claim:
An integral locking system for a firearm, the firearm having a barrel having a longitudinal axis, a bolt, a cocking piece having an integral firing pin, and a cocking piece housing, the bolt axially rotatable relative to the cocking piece housing, the integral locking system comprising: (A) a cocking piece lock rotatably disposed in a receiving slot in the cocking piece housing, the lock having an integral blade extending from the lock and an aperture adapted to receive a key, the receiving slot adapted to allow rotational movement of the lock about the longitudinal axis, but substantially no movement along the longitudinal axis; (B) the cocking piece lock having at least one aperture therein, the aperture positioned generally parallel to the longitudinal axis and at substantially the same radial distance as the aperture in the cocking piece; (C) a cocking piece plunger slidably received in the aperture; (D) the key adapted be inserted into the aperture in the lock to urge the head of the plunger fully into the cocking piece, whereby when the plunger is inserted into the aperture of the cocking piece, the lock is free to rotate relative to the cocking piece housing and when the plunger is urged into one of the lock apertures, the lock is held securely and is not free to move rotationally relative to the cocking piece housing; and (E) the cocking piece having a groove adapted to receive the blade of the lock, the groove adapted to allow the blade of the lock and cocking piece to move rotationally relative to the cocking piece housing, and stop longitudinal movement of the cocking piece when the lock is rotated to a locked position.
