Reduces muzzle brake with the aid of 4 ports on top. The 2 ports on either side direct gas horizontally keeping recoil to a minimum. The front three prongs help direct the remaining gas and concussion forward from the shooter. All these elements make up a very comfortable muzzle brake for indoor and outdoor shooters. Where other muzzle brakes direct gas only horizontally MFT's comp takes it a step further. For the best selection of AR parts and accessories, shop Palmetto State Armory!
