Flash hider? Muzzle brake? The proprietary design of SureFire’s WARCOMP SPORT flash hiders provides the best attributes of both devices. The SureFire WARCOMP SPORT incorporates the essential features of the world’s most shoot-able flash hider, the SureFire WARCOMP, in a model designed specifically for use on an unsuppressed rifle or carbine. Its expertly designed porting significantly reduces both muzzle flash and muzzle rise, helping to conceal your location and preserve dark-adapted vision, while helping you stay on target for faster follow-up shots. The WARCOMP SPORT effectively eliminates 98% of all muzzle flash, even on short-barreled rifles. All WARCOMP SPORT flash hiders are precision-machined from heat-treated U.S. mill-certified chromoly bar stock for extreme durability and corrosion resistance, and Nitride QPQ-coated for wear resistance and ease of maintenance. Installation requires no permanent modifications to the weapon system. Note: The WARCOMP SPORT is not compatible with SureFire suppressors
