Griffin Armament 5.56MM M4SD 3 Prong Flash Hider (XHP556FH3P) provides M4SD sound suppressor end users a high-performance flash suppressor/compensator alternative to compatible A1/A2 Birdcage flash suppressors. The M4SD flash suppressor provides optimal suppressor fit, enhanced flash signature reduction, and reduces muzzle climb. The focus of the Gen 3 revision was to reduce flash as much as possible.
