Abstract: A bolt assembly (1) for a self loading rifle comprises a rotating bolt (2) mounted in a bolt carrier (3), the bolt being provided with locking teeth (6) which, in use, interengage with teeth (7) on the barrel extension (8) of the weapon. The angular position of the bolt relative to the bolt carrier is controlled by a cam pin (9) which runs in a cam slot (10) in the bolt carrier. When the bolt is clear of the barrel extension it is locked in the correct angular position by a lever (11) which is pivotally mounted in the bolt carrier.

Abstract: A fire-arm having a bolt assembly which includes a bolt received by a bolt carrier and axially movable relative thereto and a T-shaped ejector set freely in a T-shaped recess in the bolt and retained in the recess by the bolt carrier while being held axially relative to the bolt by the T-shape of the extractor and the recess. In a first position of the bolt relative to the carrier the extractor is held in a first position in which it engages a cartridge for extraction from the chamber and in a second position of the bolt relative to the carrier the extractor is movable to a second position from which it can move to engage a cartridge.
