Steyr AUG is a family of firearms, first introduced in 1977 by the Austrian company Steyr Mannlicher.[2] AUG stands for Armee-Universal-Gewehr, meaning "Universal Army Rifle."[5] It is often used to refer to a specific version, especially the initial version which was 5.56 mm NATO bullpup assault rifle, with a distinctive green frame and integrated scope. It has since spawned a variety of related weapons including a submachine gun, a designated marksman rifle, and light machine guns. It has been adopted by a number of armed forces and organizations and is the standard service rifle of Austria, Australia, New Zealand, Luxembourg, Ireland, and at one time Malaysia.

The AUG is one of the first rifles to enter service designed on a bullpup principle;[5] this makes it 25% shorter than other rifles with similar barrel lengths, without compromising ballistic performance. Most versions come factory-equipped with a 1.5x magnification optical sight/carrying handle. The AUG is generally regarded as a modern ergonomic design for a combat rifle. Other features are ambidextrous controls and use of clear/translucent plastic magazines, so a soldier can see how much ammunition is left. The central design was created by Horst Wesp, Karl Wagner and Karl Möser.[5]
Barrels of the Steyr AUG can often be changed relatively easily to a different version, such as from a shorter barrelled carbine (short rifle) to a longer barrel. There is even a modification kit which allows the Steyr AUG to be converted into a submachine gun. Some versions, like the light machine gun or heavy barrel differ more substantially, including the bolt groups and trigger machanisms.
Unusually, selective fire on the Steyr AUG is controlled through the trigger as opposed to using a dedicated selector mechanism, commonly found in other selective fire rifles.[4] The trigger has two stages, pulling the trigger halfway produces semi-automatic fire, pulling the trigger all the way to the rear produces fully automatic fire. The trigger has a pull weight of about 9 pounds, which is considered heavy, although it can be lightened with aftermarket kits. The AUG is said to be well liked by the soldiers who carry it. [4]
- Steyr AUG A1— this is the standard version that was first introduced in 1977. Initially they were only green and had 20" inch barrel.[6]
- Steyr AUG A2 — the A2 is very similar to the A1, but the upper sight is removable. In its place, a Mil Std 1913 rail can be placed, or other equipment.[7]
- Steyr AUG A3 — Upper rail and front integrated Mil Std 1913. 6.8 mm Remington SPC cartridge under evaluation.[8]
- Steyr AUG P— essentially a AUG A1 but with a shorter barrel.
- Steyr AUG P Special receiver— same as AUG P but with a raised rail rather than integrated scope on the raised area.
- Steyr AUG 9 mm (AUG SMG/AUG Para)— Chambered in 9 x 19 mm differs from A1 model in barrel, bolt, magazine and a magazine well adaptor which allows the weapon to feed from Steyr MPi 69 magazines. For the 9mm version, the gun operates purely as a blowback weapon, without use of the rifle's gas system. For some time a kit of the above components was available to convert any AUG into a 9mm SMG.[3]
- Steyr AUG M203— a AUG modified for use with the M203 grenade launcher.
- Steyr AUG LSW (Light Support Weapon) — a family of light support versions of the AUG
- Steyr AUG HBAR (Heavy-Barreled Automatic Rifle [HBAR])— a longer, heavier-barreled version for use as a light machine gun but still firing from a closed bolt.
- Steyr AUG LMG (Light Machine Gun)— based on the AUG HBAR, but can fire from an open bolt, has 4X rather than 1.5x scope of regular AUG.
- Stey AUG LMG–T— same has LMG, but has rail similar to the AUG P special receiver.
- Steyr AUG HBAR–T— a designated marksman rifle based on the HBAR.
- Steyr AUG Z— a semi-automatic version somewhat similar to the A2, intended primarily for civilians.
- Steyr USR— a Steyr AUG A2 modified to meet BATF regulations.[9]
- DSTO Advanced Individual Combat Weapon— experimental weapon combining barrel, action and magazine of a Steyr F88 with an enlarged receiver and stock/body that also incorporates a multiple-shot 40 mm grenade launcher.
- Austeyr F88— Australian Army slightly modified version of the Steyr Aug A1.
- Austeyr F88-S— A version of the Australian F88 Austeyr with a picatinny rail in place of the standard optic sight to allow the attachment of various other sights (such as night vision or high-quality long range sights such as the Elcan C79 Wildcat, ACOG or Aimpoint). This version of the Steyr is notorious amongst Australian infantry soldiers, because the picatinny rail is positioned close to the cocking handle, often resulting in injured knuckles.
- Austeyr F88 GLA— Australian Army version with M203. It features an Inter-bar (armourer attached) interface, an R/M Equipment M203PI, and Knight's Armament's quadrant sight assembly to which a Firepoint red dot sight is attached. The bayonet lugs and forward vertical foregrip is removed.
- Austeyr F88-c— A carbine version of the Australian F88 Austeyr, it has a ten centimetre shorter barrel.
- Austeyr F88 A4— ADI’s Austeyr F88 A4 will incorporate multiple picatinny rails for the fitting of legacy systems such as the M203 P1 40mm grenade launcher assembly (GLA) as well as both commercial off-the-shelf (COTS) and military off-the-shelf (MOTS) sighting and numerous additional battle enhancement accessories.
