Accu-Tac's muzzle brake connects to the muzzle of a firearm that redirects propellant gases to the sides and forward to counter recoil and unwanted rising of the barrel during rapid fire. The Tank II Muzzle Brake releases gases forward and to the sides to reduce muzzle rise and improve accuracy for faster follow-up shots. It is precisely CNC machined and heat treated to withstand intense use. This 223 Remington model has a black finish.
