The Steyr Arms AUG A3 M1 (brand part no. AUGM1BLKNATOEXT) is a bullpup rifle chambered in 5.56 NATO, built with a NATO-length extended Picatinny rail for mounting optics forward of the receiver on the iconic AUG platform. Its bullpup layout keeps the 16-inch barrel while trimming overall length compared to a traditional-length rifle, making it fast to maneuver in tight spaces without giving up ballistic performance. The integrated optic base and two-position safety keep the manual of arms simple, and the black finish gives it a clean, tactical look. This is a genuinely different, combat-proven rifle platform for shooters who want something distinct from the standard AR-15.
