One of the most tested and proven weapons systems in the world achieves ultimate refinement with the introduction of the SIG516 rifle. With its chrome-lined, phosphated, military grade barrel and adjustable, four-position gas regulator, the SIG516 incorporates all of the most desirable mechanical improvements. Add to these a free-floating quad rail forend and barrel, and you have the most advanced, versatile AR-based rifle available. The SIG516 Patrol comes with a Magpul MOE stock and MOE pistol grip. As with all SIG516 Patrol rifles, it uses the SIG SAUER innovative short-stroke gas pushrod operating system, which reduces chamber debris and allows the rifle to run cleaner and cooler. This system, along with the SIG SAUER proprietary fully supported extractor enables the SIG516 to be one of the only rifles to pass NATO s Over the Beach test. A 16 chrome-lined barrel is chambered in 5.56mm NATO and is surrounded by a free-floating M1913 quad rail. The top rail is optic-ready and includes SIG SAUER flip-up iron sights.
