SureFire's advanced SF3P three-prong flash hiders provide superior performance with a patented design that significantly reduces muzzle flash-usually over 99%. Compatible with various rifle calibers and muzzle thread specifications, they are precisely machined from U.S. mill-certified heat-treated stainless steel bar stock and DLC-coated to resist erosion for reliable high performance. SF3P flash hiders feature durable tines built to endure the stresses of combat, and each one is carefully inspected for concentricity and alignment, guaranteeing a solid mounting surface for SureFire SOCOM Series Fast-Attach suppressors.
