Steyr AUG - Armee Universal Gewehr


Steyr AUG


The AUG is an Austrian bullpup 5.56mm 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 7.62mm 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 national police units.

The rifle and its variants has also been adopted by the armed forces of Argentina, Australia, New Zealand, Bolivia, Ecuador, Ireland, Luxembourg, Saudi Arabia, Tunisia, Pakistan, and the U.S. Immigration and Customs Enforcement agency.

 
The AUG, a 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 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 5.56x45mm 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.

Australian

F88 Austeyr: The Australian Army's modified version of the Steyr AUG A1. Changes for the Australian version include a bayonet lug, a 1:7 in rifling pitch as found in the M16A2 rifle, optimized for the heavier 62-grain NATO-standard SS109/M855 round and an "automatic lockout" selector that can physically disable the fully automatic position of the two-stage trigger mechanism found on the standard AUG. Contrary to popular belief the Australian issued F88 does not have the crosshair inside the "doughnut", however the New Zealand issued AUG does incorporate this feature. The AUG won a competition against the prototype of what would become the Bushmaster M17S. The components are built under license at the Australian Defence Industries factory in Lithgow, New South Wales (now known as Thales Australia).
