The JP Supercomp mitigates muzzle climb and recoil on your 9mm AR15. Flash is also reduced based on the design of the 3 prongs on the end of the Supercomp. This muzzle device is specifically set up to bring your 14.5" carbine to an overall length of 16" to avoid any NFA work, making the shortest possible setup. JP pre-drilled the barrel shroud of this compensator to make placing a pin in the device fast. The included crush washer makes timing this compensator easy and quick.
