The Steyr AUG is easily one of the most recognizable rifles in the world due to its unmistakable shape and bullpup design. The AUG A3 M2 is the semiautomatic, civilian version of the iconic Austrian rifle with all the features that made the original so great. As with all bullpup rifles, the action is located behind the trigger, allowing for a full length barrel without adding any significant overall length. The AUG A3 M2 has a length of just 28.15 inches with a heavy barrel of 16 inches. It utilizes a short-stroke gas piston operation, allowing the rifle to run cleanly by venting out gas from the front of the rifle and a dual adjustment setting ensures flawless operation even with poor quality ammunition and in adverse conditions.
