Steyr AUG

The AUG is an Austrian 5.56 mm assault rifle, designed in the early 1970s 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 1977, where it replaced the aging 7.62 mm StG 58 automatic rifle (a license-built FN FAL). In production since 1978, it is the standard small arm of the Austrian Bundesheer and various police units. It has also been adopted by the armed forces of Argentina, Australia (accepted into service in 1985 and manufactured by Australian Defence Industries in Lithgow, this Austeyr model is also in use by New Zealand), Bolivia, Ecuador (1988), Ireland, Luxembourg, Saudi Arabia, Tunisia (introduced in 1978), Pakistan and since 1988, the U.S. Immigration and Customs Enforcement agency.

The AUG, a bullpup 5.56×45mm automatic 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 AUG is a modular configuration rifle that employs a high level of polymer and advanced alloy components.

The primary variant of the rifle, designated the AUG A1, consists of six main assemblies: the barrel, receiver with integrated telescopic sight, bolt and carrier, trigger mechanism, stock and magazine.

The AUG uses the 5.56×45mm NATO cartridge and the standard 1:9 rifling twist will stabilize both SS109/M855 and M193 bullets. Some nations including Australia and New Zealand use a version with a 1:7 twist optimised for the SS109 NATO round.
