The SureFire FH556RC-1/2-28 4-prong flash hider is designed for 5.56mm weapon platforms with a 1/2-28 thread pattern. Developed for demanding military suppressor trials, this flash hider provides significant muzzle-flash reduction—typically more than 99 percent compared with a bare muzzle—helping minimize visible signature during low-light use. Its rugged design offers dependable performance for professional, duty, and recreational applications.
The four-tine configuration provides effective flash suppression while maintaining a reliable mounting interface for SureFire SOCOM Fast-Attach suppressors. Multiple bearing surfaces support proper suppressor alignment, helping promote consistent installation and reliable operation. The FH556RC-1/2-28 is compatible with .223 Remington and 5.56mm platforms when properly installed by a qualified professional.
Precision-machined from U.S. mill-certified stainless-steel bar stock, the SureFire FH556RC-1/2-28 is heat-treated for increased strength and durability. Its material and finish provide strong resistance to gas and particle erosion, supporting long service life under demanding firing conditions. The black finish complements a wide range of rifle configurations while maintaining the hard-use character expected from SureFire components.
Each SureFire flash hider is individually inspected for concentricity and alignment to support dependable suppressor mounting. The FH556RC-1/2-28 is backed by SureFire’s No-Hassle Guarantee. Verify thread compatibility, suppressor requirements, and local regulations before installation or use.
