The SureFire SOCOM SF3P Three-Prong Flash Hider in 5.56mm with 1/2-28 threads (brand part no. SF3P-556-1/2-28) is a flash hider and suppressor adapter in one. SureFire designed its patented three-prong layout to cut muzzle flash, which the company says typically exceeds 99 percent. Heat-treated stainless steel and a DLC coating make it durable enough for hard use. It is the mount for SOCOM Series Fast-Attach suppressors on a standard AR-15 muzzle thread, so one device covers both the bare and the suppressed rifle.
