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 AUGs 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.
