Sig Sauer SIG516 G3 Mohawk 5.56mm 16″ Rifle

SIG SAUER’s 516-MOHAWK is an upgraded, rugged AR-15 piston rifle that builds on the 516 line with modernized features and a new product ID. Designed and tested globally (finalized in New Hampshire), it uses a short-stroke piston with an adjustable gas system for reliable, tuneable operation. Chambered in 5.56 NATO, it comes standard with a 16″ cold-hammer-forged barrel (1:7 twist), rear/side non-reciprocating charging handle, fully ambidextrous controls, and steel-reinforced high-wear parts. Other features include a SIG Matchlite DUO curved trigger, SIG flash hider/compensator, and a free-floating M-LOK handguard — all aimed at long-term durability and field reliability.
