Griffin XHP556CTFH Gate-Lok Closed Tone Flash Hider: Advanced Flash Suppression & Suppressor Compatibility
The Griffin Armament XHP556CTFH is a high-end Closed Tone Flash Hider featuring Griffin’s innovative Gate-Lok mounting system. Threaded in the standard 1/2x28 pitch, this muzzle device is engineered for AR-15 platforms and other 5.56 NATO rifles. Unlike traditional open-port flash hiders, the Closed Tone design provides enhanced flash suppression by directing gases more effectively, resulting in reduced visible muzzle flash during low-light shooting.
The Gate-Lok system allows users to quickly and securely attach compatible Griffin suppressors without additional adapters. This dual-purpose design makes the XHP556CTFH an excellent choice for shooters who want both effective flash reduction and the convenience of rapid suppressor mounting.
