The Steyr AUG (Armee Universal Gewehr) is an iconic assault rifle of Austrian origin, designed by Steyr Mannlicher and introduced in 1977. Recognized as one of the first rifles to adopt a bullpup configuration, it redefined the standards of modern long guns thanks to its futuristic design, modularity and exceptional performance. Today, its variants – notably the Steyr AUG A2 and Steyr AUG A3 – continue to dominate battlefields and tactical operations around the world.
History of Steyr AUG
Development of the Steyr AUG began in the 1960s. Its aim was to create a standard weapon for the Austrian army, capable of replacing the StG 58 (the Austrian version of the FN FAL). The aim was to design a modular, compact, lightweight weapon suitable for modern operations.
Adopted by the Austrian army in 1977 as the StG 77, the Steyr AUG quickly established itself as a reliable and revolutionary weapon. It was exported to many countries, becoming the standard service weapon for armed forces and police units around the world, including Australia, Ireland and New Zealand.
Design and conception
One of the key features of the Steyr AUG is its bullpup configuration, in which the mechanism and magazine are located behind the trigger. This design reduces the overall length of the gun without sacrificing barrel length, offering exceptional maneuverability, particularly in confined spaces.
The rifle is made from reinforced polymers, making it lightweight yet robust. Its modular design enables the barrels to be changed quickly and various accessories added, adapting the weapon to different roles: assault rifle, sniper rifle or light machine gun.
Variants: Steyr AUG A2 and A3
Steyr AUG A2: Introduced in the 1990s, this model is an improvement on the original Steyr AUG. It features a removable rail for adding optical devices, laser pointers or other accessories. This version retains the same robustness and flexibility, while meeting modern user needs.
Steyr AUG A3: Launched in the early 2000s, the Steyr AUG A3 is an even more tactical variant. It features integrated Picatinny rails, offering complete customization for the addition of advanced optics, tactical lights or vertical grips. Ergonomics have also been improved for optimum comfort.
