The Sig Sauer 516 G3 runs a short-stroke piston system with a 3-position adjustable gas block that keeps the action running reliably across suppressed and unsuppressed configurations while reducing carbon and heat transfer to the bolt carrier. The 16" cold hammer forged barrel with FNC finish and 1:7" twist delivers consistent accuracy and long-term durability, while the SIG flash hider compensator manages muzzle rise for faster follow-up shots. Steel-reinforced high-wear components extend service life through sustained hard use.
The free-floating M-LOK handguard eliminates barrel pressure for consistent accuracy while offering versatile accessory mounting, and fully ambidextrous controls support natural operation for any shooter. Non-reciprocating rear and side charging handles and the Matchlite Duo curved trigger give this 5.56 piston-driven AR rifle a refined, competition-capable feel straight from the factory.
