This flash hider for 5.56 mm weapon platforms is the exact flash hider that SureFire developed to dominate the most rigorous suppressor trial in military history and earn the USSOCOM suppressor contract. Its four-tine design significantly reduces muzzle flash - typically greater than 99% compared to a bare muzzle - delivering extreme signature reduction and rugged dependability. With multiple bearing surfaces that ensure proper suppressor alignment, this flash hider serves as a rock-solid mounting platform for any SureFire SOCOM Fast-AttachA(R) suppressor. Precision-machined from U.S. mill-certified stainless-steel bar stock, and heat-treated for added strength, it is highly resistant to gas and particle erosion, so you can depend on it to provide years of faithful service. SureFire flash hiders are individually inspected to ensure concentricity and alignment and covered by SureFire's No-Hassle Guarantee. Features: Improved version of the US Special Operations Command suppressor trial-winning SOCOM556-RC Features the finest engineering and materials for unsurpassed performance and reliability 6.4-inch overall length optimized for superior signature reduction Designed specifically for 10-inch and longer M4/M16-variant rifles and carbines Eliminates first-round flash, a phenomenon common in most suppressors Suppresses visible flash up to 99.3% over a bare muzzle Tight tolerances and precision bore concentricity result in superior accuracy Durable high-temperature Inconel alloy/stainless-steel construction withstands full-auto use Cutting-edge internal venting reduces back pressure, cyclic rate and gas blowback to significantly reduce operating temperatures Compatible with the SureFire array of Fast-AttachA(R) mounting adapters (flash hiders, Muzzle brakes, and WARCOMPS) Fast-AttachA(R) design allows fast, secure, easy attachment and removal without tools All SOCOM556-RC2 suppressors are test-fired to verify sub-1 MOA group size and point-of-impact shift Durable construction delivers long service life Proudly designed and manufactured in the U.S.A.
