The non- reciprocating plastic cocking handle works in a slot on the left side of the receiver and is connected with the bolt carriers left guide rod.Īt the forward end is the pistol grip with an enlarged forward trigger guard completely enclosing the firing hand that allows the rifle to be operated with winter gloves. There is a short cylinder which contains a piston and its associated return spring. The firing pin is operated by a plastic hammer under pressure from a coil spring.Īn external sleeve is shrunk on to the barrel and carries the gas port and cylinder, gas valve and forward grip hinge jaw. Since the trigger is located some distance away, it transmits its energy through a sear lever which passes by the side of the magazine. The hammer group is made entirely of plastics except for the springs and pins and is contained in an open- topped plastic box which lies between the magazine and the buttplate. The second setting, illustrated with a large dot, indicates fouled conditions. The left- hand rod provides retracting handle pressure when connected by the forward assist and can also be used to remove fouling in the gas cylinder by utilizing the left- hand guide rod as a reamer.
The AUG uses a short- stroke piston system where the right guide rod serves as the action rod, transmitting the rearward motion of the gas- driven piston to the bolt carrier. The bolt also contains a claw extractor that forms the eighth locking lug and a spring- loaded. The bolt carrier itself is guided by two guide rods brazed to it and these rods run inside steel bearings in the receiver. The flash suppressors are screwed to the muzzle and internally threaded to take a blank- firing attachment. The sight is also equipped with a set of three illuminated dots (one on the front blade and two at the rear) for use in low- level lighting conditions. The rifle also has a back- up iron sight with a rear notch and front blade, cast into the top of the aluminum optical sight housing, used in case of failure or damage to the primary optical sight.
When so set, aiming at the centre of a target will produce a hit at all ranges out to 3. The sight cannot be set to a specific range but can be adjusted for windage and elevation for an initial zero and is designed to be calibrated for 3. If needed, the ALO can be pushed up to permit automatic fire.
