Built Short. Runs Strong.
The SIG516 G3 brings proven piston-driven performance to an ultra-compact platform built for speed, control, and reliability under demanding conditions.
Now available in 11.5″ Pistol and SBR configurations.
At the heart of the rifle is a short-stroke piston operating system with a 3-position adjustable gas block, engineered for consistent performance across a wide range of ammunition and environments.
Engineered to withstand hard use in demanding conditions, the SIG516 G3 features steel-reinforced components in high-wear areas, fully ambidextrous controls, and rear and side non-reciprocating charging handles for intuitive operation.
Featuring an 11.5″ cold hammer-forged barrel, free-floating M-LOK handguard, and Matchlite Duo trigger, the SIG516 G3 delivers the reliability, durability, and performance that define the SIG piston platform.
