The ACE brake is tunable– With the indicator lines located on the brake as well as the collar you can “tune” the brake to your rifle setup. What that means is that you can ensure that your rifle recoils straight up and down– every time. The indicator lines allow you to have a solid reference for how much you rotate the brake to get the perfect recoil pattern. Once you have it found simply use the allen wrench to tighten the collar down onto the brake. Now you can torque your brake on and off and it will come back to the same spot every time.

The side ports are straight keeping the blast off of the shooter and make for a much more enjoyable shooting experience. The geometry of the side ports also optimizes the three rows of holes on the top to keep your gun as flat as possible without any blast directed back to the shooter.
