The SIG516 G3 builds on the 516 series blending modern enhancements with a proven battle-tested design. Deployed in some of the harshest environments worldwide the SIG516 G3 draws on more than a decade of real world user feedback to deliver exceptional durability and reliability within its class. Chambered in 5.56 NATO the SIG516 G3 is standard with a 16′ cold hammer forged barrel with a 1:7-inch twist rate. The intuitive design of the SIG516 G3’s unique rear and side non-reciprocating charging handle allows the rifle to be easily operated in any manner in any condition. To support long-term operational use and extended reliability the rifle features steel-reinforced components for high-wear areas (cam path and feed ramp). The SIG516 G3 is standard with fully ambidextrous controls including the bolt catch magazine catch safety and charging handle. Additional on-rifle components include a SIG Matchlite DUO curved trigger SIG flash hider compensator and a free-floating M-LOK handguard.
