Product Description The Silent Steel USA FHAQDL-B-556-12X28 is a purpose-built 556 BoltLok Flash Hider designed for shooters who demand a seamless transition between open-muzzle and suppressed fire. Engineered for 5.56/.223 caliber rifles with a 1/2x28 thread pitch, this muzzle device combines the muzzle flash reduction of a traditional flash hider with the rapid-attach versatility of Silent Steel&';s BoltLok quick-detach locking system. The robust black finish and precision-machined construction ensure durability and reliable performance in demanding conditions, making it an ideal host device for compatible Silent Steel suppressors. Product Highlights BoltLok Quick-Detach System: Allows fast and secure suppressor attachment and removal without tools, maximizing operational flexibility. Effective Flash Suppression: Traditional flash hider geometry reduces visible muzzle signature for improved low-light performance. Caliber and Thread Specific: Designed specifically for 5.56/.223 caliber rifles with a 1/2x28 threaded muzzle for a precision fit. Durable Black Finish: Hard-wearing matte black finish resists corrosion and wear under repeated use. Precision-Machined Construction: High-quality machining ensures consistent alignment and repeatable point-of-impact when attaching or detaching the suppressor.
