Austrian Steyr AUG Series and Steyr AUG A1 Carbine Series

The Steyr AUG Bullpup rifle and Steyr AUG A1 features an Spz-kr type two-stage trigger (pulling the trigger halfway produces semi-automatic fire, pulling the trigger all the way to the rear produces fully automatic fire) and a safety mechanism (cross-bolt, button type), located immediately above the hand grip. In its “safe” position (white dot) the trigger is mechanically disabled; pressing the safety button to the left exposes a red dot and indicates the weapon is ready to fire. Some versions have an ALO or "automatic lockout", a small projection at the base of the trigger. This was first included on the Irish Defence Forces variant of the rifle, and soon after, the Austrian Defence Forces variant.  

Steyr AUG Austrian Rifle Originally

The Steyr AUG Bullpup 5.56mm Assault Rifle is a selective fire weapon with a conventional gas piston operated action that fires from a closed bolt. Designed as a family of rifles that could be quickly adapted to a wide variety of roles with the change of the barrel to a desired length and profile, the Steyr AUG is a modular configuration rifle that employs a high level of polymer and advanced alloy components.

Steyr Aug A1 Assault Rifle

The Steyr AUG 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 Steyr AUG A1 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 Steyr AUG A1 Assault Rifle. The Australians and the Malaysians license-produce the Steyr AUG.

Steyr AUG A1 HAR Rifle

Steyr AUG A1 and Steyr AUG A2 Assault Rifle

In 1997, the standard Steyr AUG A1 Assault Rifle was replaced in production (except in Malaysia) by the Steyr AUG A2 Assault Rifle. The Steyr AUG A2’s magazine well is modified so that it can use NATO/US magazines as well as magazines designed for the Steyr AUG and magazines like Beta’s C-Mag.
The scope/carrying handle was replaced by a MIL-STD-1913 rail, allowing the rifle to use virtually any sort of optics. However, when the Steyr AUG A2 arrived, the 13.77-inch SMG barrel was deleted from the options available to the Steyr AUG. Civilian/police semiautomatic-only versions of the Steyr AUG A1Assault Rifle and Steyr AUG A2 assault rifles and carbines are available on the civilian market in many countries; these generally have no bayonet lug, and often have their barrels permanently attached instead of being interchangeable with shorter or longer AUG barrels. In some cases, civilian versions of the Steyr AUG do not have flash suppressors, if that is necessary to comply with local laws.

Steyr AUG A3 Rifle

Steyr AUG A3 assault rifles Similar to the Notes above; however, after the November nuclear exchange, production of the Steyr AUG virtually stopped in Austria and Malaysia. For at least 20 years after the Twilight War, the only country who produced the Steyr AUG A3 assault rifles was the Austrian. The “Steyr AUG A3 assault rifles” version is also a rarity in the Twilight 2000 world, except as produced by the Australians. Similar to the Notes above; the AUG is a big hit with mercenary groups worldwide, especially the “Steyr AUG A3 assault rifles”

Steyr AUG A2 Carbine

The Steyr AUG A1 Rifle is a gas-operated selective fire rifle. A gas-pressure adaptor has a shut-off valve located on the barrel with two settings-for firing under normal or adverse conditions. It is also available in a semi-automatic version for police use.This high-tech assault rifle employs a unique 30-round, lightweight magazine made of transparent plastic which leaves no doubt as to the number of rounds one has left. The one-piece, greenish-colored stock is made of a durable plastic and houses the receiver group, hammer mechanism and magazine well.
