Australian Steyr AUG Series Assault Rifle

Steyr AUG Bullpup Assault Rifle Originally designed as a technology demonstrator, the Steyr AUG (Armee Universal Gewehr, or Army Universal Rifle), became wildly successful, and versions of the weapon ranging from submachineguns to civilian rifles were produced. It was first produced in 1978, and it became one of the few bullpup military rifles used in number by world armies. The AUG is used by Austria (where it is the standard assault rifle, and is known as STG-77), Australia, Ireland, New Zealand, Oman, Malaysia, and Saudi Arabia; in addition, British soldiers stationed in the Falklands also use the AUG. The Australians and the Malaysians license-produce the AUG. (The Australian version of the AUG is different enough from a standard AUG that is has its own entry under Australian Assault Rifles.)

The body and magazines of the AUG are made of high-impact plastic, while the internal workings and the barrel are made of high-quality steel (except for the hammer and certain other parts of the hammer unit, which are unusually made of very-high strength plastic). At the very front of the receiver is a fold-down plastic foregrip which can be used as a handguard when folded. The result is a weapon that is light, handy, yet accurate. The weapon includes a 1.5x battle sight that further improves accuracy; it is on an elevated mount and forms a part of a carrying handle.

The AUG’s trigger is two-stage: pull it back a certain distance, and you get semi-automatic fire, and pull it back all the way for full automatic fire. This can sometimes lead to “accidental automatic fire.” The gas block is also adjustable, for standard fire, a fouled chamber or barrel, and a cutoff for the firing of certain rifle grenades. The gas block adjustor is also used to replace the barrel with barrels of other lengths or otherwise remove the barrel.


Barrels can be removed and replaced in seconds (less than one combat phase). There are cutouts on either side for the ejection port and charging handle, and the fire and magazine controls may be switched from one side to the other, making the AUG ambidextrous (unusual for a bullpup weapon, though some soldiers say that the AUG is equally uncomfortable to use with either hand due to its poor ergonomics).


Several interchangeable barrels can be fitted to the AUG, allowing the AUG to perform the roles of submachinegun, carbine, heavy-barreled automatic rifle, or a sharpshooter’s rifle. In addition, a barrel exists that allows the AUG to function as a squad automatic rifle, and a parts kit that allows the AUG to be converted to a submachinegun firing 9mm Parabellum ammunition (see Austrian Submachineguns). The standard AUG uses a 20-inch barrel; the AUG Carbine has a 16-inch barrel; the AUG SMG (also called the AUG-P) uses a 13.77-inch barrel; and the HBAR has a 24-inch barrel. In addition, the HBAR (sometimes referred to as the Steyr AUG LMG Assault Rifle and Steyr AUG SAW Assault Rifle ) is equipped with a bipod.

The AUG SMG (also called the AUG-P) is often found with special receiver that better suits the extra parts needed to allow the AUG to properly function with the very short barrel; however, this redesigned receiver is not required to allow the AUG SMG to function properly.
