Description
Sig Sauer 516 G3 Pistol Features The 516 G3 Pistol is built around a short-stroke piston operating system with a 3-position adjustable gas system providing cleaner cooler and more reliable cycling than direct impingement alternatives across a wide range of ammunition and suppressor configurations. Chambered in 5.56 NATO with an 11.5-inch cold hammer-forged barrel at a 1:7 twist rate and FNC finish the 516 G3 delivers consistent accuracy and barrel longevity backed by steel-reinforced components at all high-wear areas throughout the platform. A 1/2x28 threaded muzzle ships with a SIG Flash Hider Compensator and provides a straightforward foundation for suppressor and muzzle device upgrades. The short-stroke piston pistol features fully ambidextrous controls including the safety magazine release and bolt catch accommodating left- and right-handed shooters without modification or aftermarket parts. Rear and side non-reciprocating charging handle options give the shooter flexible charging handle positioning for different optics and carry configurations without interfering with the firing cycle. The free-floating M-LOK handguard provides a rigid interference-free barrel relationship for consistent accuracy while offering broad accessory compatibility across lights lasers grips and other tactical attachments. Sig Sauer engineered the 516 G3 around the MatchLite Duo curved trigger for a refined consistent pull that improves shot-to-shot accuracy in a platform designed for both precision and rapid fire applications. The collapsed overall length of 28.3 inches and extended length of 30.3 inches give the 516 G3 a highly manageable footprint for close-quarters use vehicle operations and any application where a compact but hard-hitting 5.56 NATO platform is required. For tactical shooters who demand piston-driven reliability full ambidextrous controls and Sig Sauer s build quality in a pistol format the 516 G3 is a definitive choice.
