To commemorate the 40th anniversary of its famous AUG, Steyr Arms is introducing the STG 77 SA rifle, a limited-edition version of the venerable platform that's design to emulate the look, feel and operation of the original.
The STG 77 is the first U.S.-built production AUG variant to come standard with a 20-inch barrel. The barrels are cold-hammer forged and profiled to the original 1977 specifications, and at the muzzle is a tulip-style brake with the original "hex" check nut. Also included in the special edition is the integrated, original-profile 1.5X scope. The scope features a circle-dot reticle. Unlike the original, there's no special tool required to adjust the windage and elevation—the STG 77 reticle can be adjusted with a coin. Integrated to the top of the scope housing is a set of three-dot post-and-notch backup sights.
The STG 77 has been designed without any rails. That said, the scope can be removed and replaced with any of the five standard Steyr Picatinny rails currently available for the AUG A3 M1. Also in keeping with the original color scheme, the STG 77 features OD Green furniture with a stock that accepts Steyr's proprietary translucent magazines. The Steyr "bullseye" logo is laser engraved on the right side of the stock along with "STG77 40th Anniversary." One AUG 30-round magazine with a matching OD Green floorplate is included with each rifle.
