The SIG516 G3 builds on over a decade of proven engineering to deliver a rugged, mission-ready piston rifle. Tested worldwide and refined in New Hampshire, it features a short-stroke adjustable gas system for uncompromising reliability in harsh conditions.
Chambered in 5.56 NATO, the SIG516 G3 includes a 16” cold hammer forged barrel, fully ambidextrous controls, steel-reinforced high-wear components, and a unique non-reciprocating charging handle. Finished with a free-floating M-LOK handguard and premium on-rifle components, the SIG516 G3 sets a new standard for durability, reliability, and user-focused design in a modern sporting rifle.
