Description
Primary Weapons Systems FSC556 is an FSC compensator built for .223 Rem/5.56 NATO barrels with a 1/2×28 muzzle thread. It is designed to reduce recoil as its primary function and provide flash suppression as a secondary function. The FSC port design helps keep flash out of optics and the shooter’s line of sight, while also reducing distracting overpressure that can be felt with many compensators.
