Light machine guns family AUG «Steyr

The company "Steyr" (later "Steyr-Daimler-Pooh") with cramped cooperation with the Austrian army has developed an assault rifle StG-77. In 1978, the first batch of the rifles came to the troops. Rifle built on a modular scheme that allowed rapid remodel it to other types of guns. This rifle is better known under the designation AUG (Armee Universal Gewehr — «Universal Army rifle"Or a" universal army gun "). In a family of tools AUG 5.56 mm are: shortened Machine (barrel length is 350 mm), a carbine (barrel 407 mm) assault rifle (trunk 508 mm), light machine gun (it has a heavy barrel, its length equals 621 mm). In all variants of used magazines for 30 rounds, a light machine gun is also used to store 42 rounds. All instrument is equipped with a telescopic sight, made with carrying handle.

The idea, planted by developers was to create a light in the appeal and carrying a modular instrument that can be used on military vehicles, and the details will just change its configuration. So, for the realization of the fire from the left shoulder was necessary to rearrange the ejector also turn the cover window ejection port. This is a common operation could be carried out in the field criteria. AUG in almost all respects was the first: the first modular system, the first instrument of the scheme "Bullpup" having gone into mass creation and entered service, the first serial model, which had as main optical sight and a wide application in the design of plastics. Wide butt, which also gives support to the cheek hand, allows you to comfortably put gun arrow with a different physique.

The design tool comes 6 modules (parts): the trunk (without bipod or with them), receiver, trigger, bolt, butt (the bed) and a shop. The barrel is made of cool rotary forging, which is designed "Steyr", and has a chrome-plated. The barrel is mounted external coupling, which is put in a hot state. In the sleeve manufactured gas escape hole, a gas regulator and a camera. On the coupling installed articulated arm holding the front handle. Gas piston and revertible spring associated therewith are placed in the gas chamber. Eight projections breech cling to the locking collar receiver. This coupling to the rear side is engaged with the shutter. To the front of the gas regulator handle is pivotally mounted retention and can be folded under the barrel (forward), playing the role of the forearm. Hold the handle consumed in substitution of the barrel. The receiver is manufactured by molding under the highest pressure aluminum. For charging handle on the left side has a slit. Pen Carrying and sight made to the receiver.

In automation AUG implemented scheme powder combustion gases from the bore. Unusual for this system is to shift to the right of the gas chamber and piston installation on one of the guide rods. Gas regulator may be in the 2-positions — use larger opening in the event of contamination mechanism. The barrel is locked by turning the shutter has produced seven lugs, instead of the projection of the eighth — the ejector. The shutter is operated during movement of the projection into the recess of the slide gate frame. It has a pair of guide rods placed inside the revertible springs. The rods fit into grooves formed on the receiver. Left pin engages with the latch with handle cocking the shutter in this case, you can manually return to the original position, but the handle of the weapon is not moving. The gas piston rod — right pin, left pin — used for cleaning tools to clean the gas chamber.

Trigger assembly is installed in the housing through the hole in the butt. Hole locked rubber lining. USM feature is that it's parts, not including axles and springs are made from plastic and enclosed in an open plastic housing, located between the cover plate of the butt and shop. Valve assembly moves over this case. The force of the trigger sent to sear through the double trigger rod extending along the edges of the store. Under the action of the coil spring plastic hammer pounding on the firing pin. Translator fire mode is absent. Shooting single shots made during the half-pedal to trigger the primary trigger sear. Subsequently, pressing the trigger sear worked in a continuous fire. It sought from the firing of certain abilities. Self-timer is not allowed to create a shot until the full locking the barrel bolt. The mechanism of the changes by setting trigger another type. On the pistol grip trigger is set, equipped with 2 rods extending along a shop window on the guide. Above the handle has a push-button lock. Locking trigger rods occurs when the button is released on the right.

Made of plastic store (not counting the spring and feeder). Housing store to be transparent, thus providing control over the flow of cartridges. Butt (bed) — a single molded piece. In its front part is the pistol grip with trigger guard, which fits all hand arrow. The latch is located in front of the receiver store, serves to detach from the stock receiver. Above the receiver has a pair of windows serve to ejection port, one of the windows closed plastic cover. Channel for the movement of the shutter and trigger mechanism installed in the rear of the stock. Swivel pin fastened his head butt.

1.5x optical sight has a grid as dark rings, which can be for a small clearance time to put on the human figure at a distance of 300 meters. With all of this aim must be to delay in the center of the circle. In addition to the upper surface of the sight is made immutable mechanical sight serves to frisky pickup during close combat. A special receiver that has a thin arm in place telescope allows the use of all types of optical, collimating and night sights in the set are six-ZF 69.

For firing blank ammunition is screwed into flame arrestor device, which overlaps the muzzle so that the powder gas pressure allows the operation of automation. The muzzle of t
he barrel assault rifle can be equipped with a bipod attachment for cutting wire — "ersatz" machine gun.

Light machine guns family AUG «Steyr" connected voedinyzhdy title "5.56-mm universal system of fire support." These machine guns are made in different ways.

In both versions of the configuration of machine guns can be made that enable you to fire from the rear sear. With all of this in the stock module is installed brand new trigger assembly, and the module is equipped with the latest bolt handle. Details for these configurations are supplied by the manufacturer for their installation requires the least minute. Bimbo trigger assembly is suitable for installation in a previously released copies of the AUG. Shooting from the rear sear on fighting properties guns are not affected.
