The G2 Heathen was developed with the competition and long range shooter in mind. With the time-proven success of the original  Heathen Brake Design we have made changes to further improve performance in competition and large magnum rifle applications.

Integral grooves to mount the optional brass tuning weight:

The Brass Tuner is purchased separately and can be adjusted with the same principle as a traditional “tuner.” The concept of tuning the barrel harmonics is a proven concept and now an integral part of the G2.

The design goal of the Original Heathen succeeded to provide optimal recoil reduction, reduced ground disturbance, decreased muzzle jump and blast directed back at the shooter. We have taken the design of the G2 a step further with the following features compared to our original 5-Port 1.125″ Heathen Brake:

50% increase in 1st port volume

24 degree increase in upward angle cut-out of port window to reduce muzzle rise

12% increase in “floor” or bride area on the bottom of the brake to reduce blast downward causing ground and debris disturbance

Front wall of the 1st port is angled at 22 degrees to direct gasses slightly upward reducing muzzle rise while still maintaining a shielded area to avoid direct disturbance of the shooters line of sight and ability to see “trace.”

With the tuner installed, the total weight of the brake is 9.5OZ!  РONLY 1/2 OUNCE MORE THAN OUR ORIGINAL 5-PORT 1.125 HEATHEN
