Steyr Mannlicher AUGM1BLKNATOEXT: The iconic bullpup-style Steyr AUG has been one of the most recognizable rifles in the world since its adoption by the Austrian army in 1977 and is now available for civilian use as the Steyr AUG A3 M1. The short-stroke gas-piston operation of the AUG runs exceptionally cleaner by nature because all of the operational exhaust gas vents out of the front of the rifle. It also features a quick-change barrel with a collapsible forward grip as well as a two-position cross-bolt safety that locks the trigger. This NATO version rifle accepts genuine Steyr AUG magazines as well as standard Stanag (AR) magazines. This firearm is chambered in 223 Rem/5.56 NATO, has a 16\" barrel with a black metal finish, a black synthetic stock, and an extended trail for optics.
