    The advanced SureFire SF3P-556-1/2-28 three-prong flash hider, which fits M4/M16 weapons and variants with 1/2x28 muzzle threads, features a patent-pending design that greatly reduces muzzle flash—typically greater than 99%—when compared with a plain muzzle. Boasting robust tines built to withstand the rigors of combat, the SF3P-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 mm Fast-Attach® suppressors, the SOCOM556-RC model having placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command.

    Precision machined from US mill-certified heat-treated stainless steel bar stock—and including high-precision single-point cut threads for optimum thread interface—the SF3P-556-1/2-28 flash hider is given a black Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning, even after extreme use.

    When used in conjunction with a SureFire SOCOM Series suppressor, the patent-pending design of the SF3P-556-1/2-28 provides multiple bearing surfaces to ensure superior suppressor alignment and to prevent the audible ringing of tines inside the suppressor. A rear labyrinth seal minimizes potential carbon buildup in the indexing system and facilitates suppressor removal after extended firing.

    FITS: M4, M16 and variants

    MOUNTS: All SureFire SOCOM Series 5.56mm/.223 caliber sound suppressors

    NOTE: SureFire SOCOM Series Fast-Attach sound suppressors, flash hider/suppressor adapters, and muzzle brake/suppressor adapters are not compatible with previous SureFire Fast-Attach sound suppressors, muzzle brakes, or flash hiders.
