Flash hider? Muzzle brake? The proprietary design of SureFire’s WARCOMP flash hiders/suppressor adapters provides the best attributes of both devices. WARCOMPs deliver superior flash reduction and significantly reduce muzzle rise, helping to conceal your location, preserve your dark-adapted vision and keep you on target for faster follow-up shots. They effectively eliminate more than 98% of all muzzle flash, even on short-barreled rifles, and their port direction can be optimized for virtually any shooting style.
