Steyr Arms AUG A3 M1 5.56 NATO / .223 Remington® Semi-automatic Rifle with Short Rail
The AUG A3 M1 delivers all the classic features that established it as the pinnacle of modern rifle design, like the quick-change barrel, simple left-hand conversion and easy disassembly, plus an 11-slot short rail for forward-mounted optics. Being a bullpup, the AUG A3 M1 boasts overall length of just 28.15", including its 16" heavy barrel, making it at least 8 inches shorter than an M4 carbine with a comparable-length barrel.
So why register a Short Barreled Rifle (SBR)? 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 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.
