SureFire’s FH556RC-1/2-28 Flash Hider is the exact same flash hider that dominated the most rigorous suppressor trial in military history and earned the USSOCOM suppressor contract. When compared to a bare muzzle, the FH556RC-1/2-28 Flash Hider reduces muzzle flash by up to 99% thanks to its 4-tine design. This flash hider is outfitted with multiple bearing surfaces to ensure proper suppressor alignment, and serves as a solid mounting platform for any of SureFire’s SOCOM Fast-Attach suppressors. In addition, the FH556RC-1/2-28 Flash Hider features a mill-certified stainless-steel bar stock construction and is heat-treated for durability, as well as resistance to gas and particle erosion.
