The
Steyr AUG is an Austrian bullpup 5.56mm assault rifle, designed in the 1960s by Steyr Mannlicher GmbH & Co KG (formerly Steyr-Daimler-Puch). The AUG (
Armee-Universal-Gewehr—"universal army rifle") was adopted by the Austrian Army as the
StG 77 (
Sturmgewehr 77) in 1978,[3] where it replaced the 7.62mm StG 58 automatic rifle (a licence-built FN FAL).[4] In production since 1978, it is the standard small arm of the Austrian
Bundesheer and various national police units.
The rifle and its variants have also been adopted by the armed forces of Argentina, Australia, Bolivia, Ecuador, Ireland, Luxembourg, Malaysia, New Zealand, Saudi Arabia, Tunisia, Pakistan, and the U.S. Immigration and Customs Enforcement agency.

AUG P is available to the civilian and law enforcement markets. It features a shorter, 407 mm (16.0 in) barrel and a modified bolt, carrier and trigger assembly that will only allow semi-automatic fire. The rifle also has a slightly different optical sight that features a reticule with a fine dot in the centre of the aiming circle, allowing for more precise aiming.
