The Sig Sauer 516 G3 Mohawk is a 5.56 NATO semi-automatic rifle built around a short-stroke piston system that sets it apart from direct-impingement designs. Born from over a decade of Sig's internal engineering work, the Mohawk combines proven reliability with modern ergonomics—making it equally at home on the range, in the field, or as a dependable patrol and duty rifle. If you want a piston-driven AR platform that handles extreme conditions without flinching, this is the rifle to consider.
The 16-inch cold hammer-forged barrel (1:7 twist) comes ready to shoot with a SIG Flash Hider-Compensator. Ambidextrous controls throughout—charging handle (rear and side non-reciprocating), bolt catch, magazine catch, and safety—mean left- and right-handers operate it equally well. The free-floating M-LOK handguard gives you clean sight lines and versatile mounting options for lights, lasers, or grips. Steel-reinforced components at high-wear areas (cam path and feedramp) extend service life, while the adjustable gas system lets you dial in performance for different ammunition or conditions. A Matchlite Duo curved trigger and 6-position Magpul DT stock round out a rifle that prioritizes user convenience without sacrificing durability.
At 7.7 pounds and 36.5 inches overall (33 inches collapsed), the 516 G3 Mohawk balances maneuverability with controllability. It ships with one 30-round polymer magazine and accepts standard AR-15 magazines. Black anodized receiver, textured grip, and Picatinny rail make it a solid foundation for optics and accessories.
