The FH556-212A is a high-performance flash hider for the Colt Commando, C8 SFW, M4, M16, HK416, and 5.56mm (.223 cal.) semi-auto, bolt-action, or assault rifles with Mil-Spec 1/2-28 muzzle threads. It also serves as a precision, rock-solid adapter mount that enables rapid no-tools attachment of SureFire FA556K, FA556-212, FA556MG, or MINI suppressors to rifles with the same muzzle thread configuration.

The end of this adapter has closed prongs, with the period classic "chipped" prong, like the Knights Armament NT4 flash suppressor.

SureFire flash hiders deliver superior muzzle flash suppression. This provides three benefits—minimizing degradation of your night-adapted vision, helping to conceal your position, and reducing muzzle rise. Machined from heat-treated stainless steel, finished in a tough, corrosion-resistant coating, all SureFire flash hiders are extremely resistant to gas and particle erosion and will perform perfectly for thousands of rounds. 

This is the longer of the two Surefire legacy flash hiders.  This is well positioned to be pinned and welded to a 14.5" barrel to extend the barrel to 16". 

NOTE: SureFire muzzle brakes and flash hiders also serve as adapter mounts for Fast-Attach® sound suppressors. This muzzle device is not designed to work with SOCOM series suppressors however, the FH556-212A will work with the RC Series of suppressors. The Ratcheting system works but will not index as these do not have the notch like the current offerings from Surefire.
