AUG has been developed since the late 1960s by the Austrian
Steyr-Daimler-Puch company in conjunction with the Austrian Army.
The AUG stands for Universal Army Rifle. This assault rifle has been
adopted in 1977 as the StG.77. Its production commenced in 1978. It
replaced the obsolete StG.58 assault rifle, which was a
license-built version of the
Since its introduction the AUG gained serious popularity. It had
been adopted by a number of countries. This weapon is license
produced in Australia as the
Lithgow F88, commonly known as Austeyr.
The AUG can be considered as the most commercially successful
bullpup design to date.
AUG is chambered for the standard NATO 5.56x45 mm round. It is a
gas operated, selective fire rifle with bullpup layout. This weapon was
considered to be revolutionary in many respects when it first
appeared. The Steyr
AUG made its name for its reliability, good ergonomics and decent
AUG has a modular design. It was designed as a family of rifles that
could be quickly adapted to a variety of roles by simply changing
the barrel. There are four basic barrels. The standard rifle barrel
is 508 mm (20") long. Later include a compact 350 mm (13.7") barrel ,
407 mm (16") carbine barrel, and the 621 mm (24.4") light machine gun barrel. The last mentioned is fitted with integral folding bipod. Barrel replacement takes
only a few seconds.
has a plastic housing. It is worth mentioning that internal design
also employs a high level of synthetic and advanced alloy
components. When this weapon began to receive widespread public
attention in the 1980s, it became the media sensation around the
world, but not because of the weight savings and ergonomical
improvements that composite materials allowed for. Instead,
widespread hysteria broke-out over the supposed ability of this
weapon allowing anyone to smuggle them through metal detectors and
x-ray machines, because they were "made of plastic". It was either
overlooked or ignored that the AUG contained more steel than most
submachine guns. It was also somehow forgotten that x-ray machines
had no difficulty detecting non-metalic objects.
assault rifle is fully ambidextrous. There are two symmetrical
ejection ports, one of which is always covered. Enlarged triggerguard of this assault rifle allows to fire wearing winter
button is located above the pistol grip. The AUG has got no separate
fire mode selector. The trigger itself is used to control the mode
of fire. Pulling it half the way, will result in a single shot,
while the full pull will result in full-auto fire.

30 rounds. A light machine gun version is fed from extended 42 round
magazines. Both of these magazines are interchangeable.
is fitted with integral telescopic 1.5x magnification sight as a
primary sighting equipment. It is designed to be calibrated for 300
m range. At the top of the sight housing there is a back-up iron
sight, used in emergency.
Army rifles had no bayonet lug, however some export versions were
fitted with bayonets. Rifles equipped with 407 mm (16") and 508 mm
are capable of launching
barrel-mounted riffle grenades. A modified AUG is compatible with
the US M203PI
40-mm underbarrel grenade launcher. It is a version of the M203A1.
The AUG could not mount the original US
because the rifle is too short.
