With 16 numbered slots, the M1 High-Rail version was designed to accommodate the widest range of optic choices, from a high-magnification scope to a short-eye-relief tactical scope mounted at the rear to a holographic red-dot sight coupled in tandem with a secondary multiplier. The High-Rail extends 2.57 inches back from the receiver and sits 0.820 inches over the stock comb.
The AUG A3 M1 is built by Steyr Mannlicher-trained gunsmiths in Steyr Arms
PLEASE NOTE: Standard Steyr AUG rifles require Steyr made A3-M1 magazines, they will not accommodate standard Stanag or AR magazine. NATO Steyr AUG rifles will work with any Stanag or AR magazine, they will not work with the proprietary Steyr AUG magazines.
