5/8x24 Slabbed Mini Magnum "Muscle" Brake

The Mini Magnum "Muscle" brake is the perfect addition to your sporter contour barrel.  The first port is 90 degrees to direct the blast/concussion away from the shooter with the proceeding ports being angled to further reduce recoil. 

This is a new thread configuration for the Mini Magnum Muscle Brake.  It will fit a muzzle diameter of .685" to .850". 

This is the same size as the original Mini Mag, just the thread size is different.  

Needs timed, blended and bored out by a competent gunsmith.
