The Accu-Tac Tank ll Muzzle Brake is precisely CNC machined to exact tolerances. Heat treated to withstand intense use. The Tank ll releases gases forward and to the sides to reduce muzzle rise and improve accuracy for faster follow-up shots. Full auto fire is possible with massively reduced recoil and muzzle climb, meaning that all shots fall on target. Decreased muzzle blast gasses mean that flash signature is also reduced.
