If a traditional birdcage flash hider is what you want, SureFire's WARCOMP-556-CTN significant reduces muzzle flash with every shot fired and helps reduce muzzle rise for easier target tracking and faster follow-up shots. Neutrally ported to aid in recoil management, it mimics that of a traditional birdcage flash hider while providing a rock-solid mounting option for SOCOM Series Fast-Attach(R) suppressors. Wrench flats machined into the sides of the adapter allow for easier installation. The WARCOMP-556-CTN delivers the performance and durability you can trust.
