Round Mini Magnum Muscle Brake (5/8x24 Threads)


 Product Description

Now fit a Muscle brake to your factory magnum rifle! Was designed to fit factory sporter weight barrel contours with muzzle dia. of .685" to .990". This brake is very close in size to the mini, just a tad longer for the increased port volume.  This brake was designed to work with magnum cartridges, yet maintain a smaller profile. Where the original mini excelled with the smaller chamberings, this new design should be perfect for sporter barrels in WSM and standard Magnum cartridges. It will also reduce the recoil on the Ultra Mags to an acceptable level.


5/8x24 threads

1.00" OD.  Can be turned down to .850"
