The SureFire 3-Prong Flash Hider (SF3P Series) is a precision-machined muzzle device designed for M4/M16 and AR-pattern platforms that delivers exceptional flash suppression while also serving as a mounting interface for SureFire SOCOM Fast-Attach suppressors. Constructed from heat-treated stainless steel with a durable DLC coating, it provides outstanding resistance to corrosion, heat, and erosion during heavy firing schedules. The open-tine three-prong design helps eliminate over 99% of visible muzzle flash, reducing shooter signature and preserving low-light vision, while precision single-point threads and multiple bearing surfaces promote consistent alignment and reliable suppressor attachment. Made in the USA, the SF3P is engineered for professional-grade durability, accuracy retention, and dependable performance in demanding duty, training, and defensive applications.
