Sig Sauer 516 G3 SBR 5.56 11.5 Barrel 30-Rounds

Overview

Sig Sauer 516 G3 SBR Features The 516 G3 SBR 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 SBR 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 SBR features fully ambidextrous controls including the safety magazine release bolt catch and charging handle accommodating left- and right-handed shooters without modification or aftermarket parts. A 6-position Magpul DT stock provides a familiar adjustable length of pull across multiple shooter sizes and load-out configurations while the AR-compatible reduced angle pistol grip delivers a comfortable ergonomic firing position. 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 SBR 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 28.5 inches and extended length of 31.8 inches give the 516 G3 SBR a highly manageable footprint for close-quarters use vehicle operations and any application where a compact but hard-hitting 5.56 NATO SBR is required. For tactical shooters who demand piston-driven reliability full ambidextrous controls and Sig Sauer s build quality in a registered short-barreled rifle configuration the 516 G3 SBR is a definitive choice.
