Cover Your Position. SureFire’s advanced SF3P three-prong flash hiders deliver superior performance with a patented design that greatly reduces muzzle flash — typically more than 99%. Available for use with a variety of rifle calibers and muzzle thread specs, they are precision machined from U.S. mill-certified heat-treated stainless steel bar stock and DLC-coated to resist erosion for consistent high performance. SF3P flash hiders feature robust tines built to withstand the rigors of combat, and every SF3P is carefully inspected for concentricity and alignment, ensuring a rock-solid mounting surface for SureFire SOCOM Series Fast-Attach® suppressors.
