Flash hider? Muzzle brake? The proprietary design of SureFire's WARCOMP SPORT flash hiders combines the best features of both devices. The SureFire WARCOMP SPORT includes the key elements of the world's most shootable flash hider, the SureFire WARCOMP, in a model specially made for use on an unsuppressed rifle or carbine. Its expertly designed porting greatly reduces both muzzle flash and muzzle rise, helping to hide your position and maintain dark-adapted vision, while allowing you to stay on target for quicker follow-up shots. The WARCOMP SPORT effectively reduces 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 superior durability and corrosion resistance, and Nitride QPQ-coated for enhanced wear resistance and easier maintenance. Installation requires no permanent modifications to the weapon system. Note: The WARCOMP SPORT is not compatible with SureFire suppressors.
