The Steyr AUG A3 M1 is an iconic bullpup rifle that packs a full 16-inch barrel into one small package with an overall length of 28 inches. Our motto is “Why SBR?” Don’t sacrifice velocity for a tiny barrel. The AUG’s short-stroke gas piston operating system allows the rifle to run clean and cool, resulting in less wear and tear on the rifle along with a reduced cleaning time. The adjustable gas regulator easily allows the AUG to be reliably operated dirty or clean, either suppressed or un-suppressed. With the quick-change barrel design, various barrel lengths of 16, 18, 20 or 24 inches can be quickly swapped out to accomplish any mission.
