The Sig Sauer SIG 516 G3 5.56 NATO 11.5" 30RD SBR is a compact, piston-driven AR-platform rifle built for shooters who demand clean operation and dependable performance. Its short-stroke gas piston with a three-position adjustable gas system keeps the action running smoothly across a wide range of ammunition, while the cold hammer-forged, 11.5-inch threaded barrel is capped with a Sig flash hider compensator for controlled muzzle rise.

This SIG516 G3 configuration features a free-floating aluminum M-LOK handguard for mounting lights, grips, or other accessories without affecting barrel harmonics. Fully ambidextrous controls, rear and side non-reciprocating charging handles, and a six-position adjustable stock support comfortable handling for a variety of shooters and shooting positions. With its 30-round capacity and optics-ready upper, this rifle is well suited for training, range use, and professional-style drills, all backed by Sig Sauer’s reputation for precision engineering and reliability.
