The Sig Sauer 516 G3 in Bronze is a semi-automatic, short-stroke piston-driven AR-platform rifle chambered in 5.56 NATO, featuring a 16-inch cold hammer forged barrel with a 1:7 twist rate and a distinctive Bronze Cerakote finish on the upper and lower receivers. Built on more than a decade of piston-rifle engineering and refined in New Hampshire, the 516 G3 delivers battle-tested reliability through its adjustable gas system, allowing the shooter to tune gas settings across varying ammunition and environmental conditions. The rifle features a free-floating M-LOK handguard, a full-length Picatinny top rail, and a steel-reinforced non-reciprocating side and rear charging handle. Fully ambidextrous controls — including the safety selector, bolt catch and release, magazine release, and charging handle — make the rifle equally accessible for left- and right-handed shooters. The SIG Matchlite DUO curved trigger, 6-position Magpul DT stock, and included SIG flash hider/compensator round out a feature-rich, mission-ready package.
