    摘要： A shot-gun (1) with gas take-off has a fore end stock (20) which is movable longitudinally of the barrel (2) and lockable selectively in each of two positions: in one position, gases from the discharge of a cartridge in the gun, bleed from the barrel into the chamber (16) of a piston/cylinder unit (8, 5) to drive the piston (8) to operate an arming rod (4) of the shot gun automatically. In the other position, a valve member (30) prevents the discharge gases from entering the cylinder chamber, these gases being vented to the external environment: the stock is rigidly locked to the piston for manual operation of the arming rod by "pump" action on the stock in this latter position.

    摘要： A gas actuated pistol with a barrel unit defining a path for gases present proximate a breach end of the barrel unit to an open end below the bore of the barrel unit proximate the unit's muzzle end. The barrel unit of the pistol includes front locking means with recesses designed to accommodate side walls of the front end of a frame unit which forms part of said pistol.

    摘要： A firearm which fires projectiles (70) from a demountable disc magazine (63) for caseless ammunition rotatable about an axis transverse to the axis of the bore of the firearm barrel (2). The firearm has a gas reciprocated barrel assembly including mounting (35, 36, 38) means for a magazine, a bi-directional reciprocating cycle of the barrel assembly moves a magazine positioner (24) through a lock-unlock-lock sequence and a magazine (63) when mounted in the firearm into and out of engagement with a magazine indexing means (66) whilst the positioner (24) is unlocked in order to sequentially align peripheral projectile apertures (69) in the magazine with the bore of the firearm barrel (2).
