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, an ambidextrous rifle platform with an adjustable short-stroke, gas-piston operation chambered for 5.56x45mm (.223 Remington). The multi-configurable M1 variant of the AUG A3 platform is the latest generation of the venerated bullpup platform. Utilizing an optics attachment platform similar to the rare and much-sought-after AUG A2, the AUG A3 M1 is available from the factory with an Extended Rail. The AUG A3 M1 boasts an overall length of just 28.15 inches, including its 16-inch heavy barrel, making it at least 8 inches shorter than an M4 carbine with a comparable-length barrel. 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. The AUG's matching, yet opposed, stainless steel operation and guide rods affixed to the bolt carrier glide effortlessly inside the receiver for unparalleled smoothness in operation as well as exceptional reliability. Dual gas-adjustment settings ensure its operation, even with the dirtiest ammunition and in adverse conditions. The AUG A3 M1 has all the classic features and benefits that established it as the pinnacle of modern rifle design, including expedited disassembly as well as simple conversion to left-hand operation, which requires replacement of the standard bolt with the optional left-eject bolt and swapping the ejection-port cover. 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. The AUG A3 M1 stock, cocking piece and forward grip are made of highly durable synthetic and are available in Black, Green, Mud and White colors. This model uses STANAG type magazines (standard AR-15 magazines).
