This is the new Round 5 Port Magnum "Muscle" Brake. It is a replacement for the old 4 port magnum that was a hit with the chey tac shooters. Anything burning over 100 grains of powder will have its recoil severely reduced with this brake. The first port is 90 degrees to direct the backblast/concussion away from the shooter with the proceeding ports being angled to further reduce recoil. This results in a very shooter friendly brake that has top level recoil reduction as well.
1.00x20 threads.
This brake will work with muzzle diameters from .830-1.500
This Brake was used by 2 of the top 10 shooters at the King Of 2 Miles shooting match in Raton New Mexico this year. Derek Rodgers was one of them and got 1st place.
