SIG Sauer SIG516 G3 Semi-Automatic Rifle 5.56mm NATO 16″ Barrel Black 30+1

The SIG Sauer SIG516 G3 is a premium, gas-piston operated semi-automatic rifle chambered in 5.56mm NATO, delivering the legendary reliability and precision engineering that SIG Sauer is renowned for worldwide. Built around a 16-inch barrel and finished in a durable matte black, this rifle is engineered for law enforcement professionals, competitive shooters, and serious enthusiasts who demand nothing less than top-tier performance.

Unlike traditional direct impingement AR-platform designs, the SIG516’s short-stroke gas piston system keeps heat and fouling away from the action, resulting in a cooler, cleaner, and more reliable operation even under sustained fire. The G3 configuration represents an optimized generation of the SIG516 platform, incorporating refined ergonomics and component quality that set it apart from the competition.
