The SIG Sauer SIG516 Patrol Gen 2 stands out for its reliable short-stroke gas piston system, cold-hammer-forged chrome-lined barrel, and robust 7075-T6 forged receivers. Discontinued in 2019, Gen 2 rifles like this one have become desirable to shooters and collectors who appreciate SIG’s adjustable four-position gas regulator, proven NATO “Over-the-Beach” reliability, and a build quality adopted by several international special units.

The short-stroke piston system keeps fouling out of the action and offers four gas settings, including a suppressed mode, for dependable cycling in varied conditions.
Its 16-inch cold-hammer-forged, chrome-lined barrel is threaded 1/2-28 and paired with a 1:7 right-hand twist, giving the rifle long service life and consistent accuracy with the full range of 5.56 NATO and .223 Remington loads.
A free-floating quad-rail aluminum handguard and continuous top Picatinny rail run from the receiver to the gas block, providing ample real estate for lights, lasers, or optics of your choice.
The forged 7075-T6 upper and lower receivers feature a Type III hard-coat anodized finish, while the six-position collapsible stock and Magpul MOE grip provide a familiar AR-15 style handling with a 13.75-inch length of pull.
Marked with the 20G serial prefix identifying the Gen 2 civilian production block, this rifle represents the final production generation of the SIG516 series.
