This compensator was designed to reduce felt recoil and eliminate muzzle rise for faster follow up shots on target. This muzzle brake is designed for low power-factor ammo most commonly used with PCCs which doesn't produce as much gas. It has three vertical expansion chambers to divert as much of the gas upward to keep the muzzle flat. After the bullet is fired, the gasses have a tendency to follow the bullet in its forward direction. To divert those gasses we need a flat surface so that gas particles can hit a wall and change their direction. The Equalizer comes with a cleaning tool facilitating easy cleaning after every shooting session. The hole is made to a tight tolerance of 9,6mm so that bullets with an approx. diameter of 9,05mm have about 0,25mm of space to travel between compensator ports. Choose between 1/2 28 TPI, 1/2 36 TPI and 5/8 24 TPI. Please check our barrel thread reference.
