Surefire 5.56mm 3 Prong Flash Hider - M4/M16/AR15 - 1/2-28 Threads
Precision machined from US mill-certified heat-treated stainless steel bar stock, the SureFire SF3P-556-1/2-28 three-prong flash hider was designed to fit the M4/M16/AR15 weapons and variants. The SF3P-556 features a patent-pending design that greatly reduces muzzle flash—typically greater than 99%—when compared with a plain muzzle. Built to withstand the rigors of combat, the SF3P-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 mm Fast-Attach suppressors.
FITS: M4, M16 and variants with 1/2-28 muzzle threads
