context_page_description: The Steyr AUG is an Austrian 5.56×45mm NATO bullpup assault rifle, designed in the 1960s by Steyr-Daimler-Puch and now manufactured by Steyr Mannlicher GmbH & Co KG.
  It was adopted by the Austrian Army as the StG 77 in 1978, where it replaced the 7.62×51mm NATO StG 58 automatic rifle. In production since 1978, it is the standard small arm of the Austrian Bundesheer and various national police units. Its variants have also been adopted by the armed forces of dozens of countries.
  Steyr AUG importation into the U.S. began in the 1980s as the AUG/SA. President George H.W. Bush banned the AUG via an executive order under the 1989 Assault Weapon Import ban. Six years into the ban, AUG buyers gained a reprieve as cosmetic changes to the carbine’s design allowed importation once again. Changes included the pistol grip being changed into a thumbhole stock, and the barrel left unthreaded to prevent attachment of flash suppressors and silencers. The ban sunsetted in 2004, and in 2008 Steyr Arms worked with Sabre Defense to produce parts legally in the U.S.
context_section_description: The Steyr AUG is a bullpup assault rifle chambered in 5.56×45mm NATO. It was introduced in 1978 and was adopted by the Austrian Army and was designated as the StG 77 in 1978, then it was later adopted by several military agencies around the world.
  The Steyr AUG A1 is an improved variant of the AUG and was introduced in 1982. It is available with a choice of olive or black furniture.
  The Steyr AUG M203 is an AUG A1 fitted with the M203 grenade launcher.
  The Steyr AUG AG-C is an AUG A1 fitted with the AG-C grenade launcher.
  The Steyr AUG A2 features a redesigned charging handle and a detachable telescopic sight which can be replaced with a MIL-STD-1913 rail. Due to its modularity, a 24-inch barrel can be used and a Picatinny rail section can be fitted instead of the folding grip, where a bipod can be installed. The rifle was introduced in December 1997.
  The Steyr AUG A3 features a MIL-STD-1913 rail on top of the receiver and an external bolt release.
  The Steyr AUG A3 SF also known as the AUG A2 Commando, features an MIL-STD-1913 rails mounted on the telescopic sight and on the right side of the receiver, and includes an external bolt release. The integrated telescopic sight is offered in 1.5× or 3× magnification.
  The Steyr AUG A3-CQC was a prototype development of the AUG A3 and was first displayed by Steyr at the SHOT Show 2006. It differs in having a railed handguard attached ahead of the receiver. Due to the need to remove this extra railed section in order to strip the rifle for cleaning, it featured a quick detach lever mounted on the left side to remove the rail. Due to the concerns over the extra cost and weight, along with potential issues with the reliability and consistency of the detachable handguard, the prototypes received little interest and were last seen promoted by Steyr in 2008 and likely has been cancelled. In total only 5 prototypes were made, four with standard 18-inch barrels, and one with a longer heavy marksman barrel and a 20-round magazine. In 2012 the American company PJA obtained the 5 original prototypes from Steyr and reverse engineered them in order to produce a US-made AUG A3-CQC and conversion kits.
