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.
