originial closed-tine 'chipped' flash hider, for use with Surefire Fast Attach legacy suppressors.
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 Armamement 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". This is a legacy device, and we do receive these from Surefire, but due to their legacy status, the pricing on this model is quite a bit higher than for current prodcution Surefire flash hiders.
THIS MUZZLE DEVICE WILL NOT SUPPORT THE Surefire SOCOM Suppressors.
