Does the barrel need to be removed from the action to thread the muzzle for a brake ? I have a R700 in .300 WinMag that I would like to add a brake to . The barrel only has a couple hundred rounds down it . I'm wondering if it could be done without too much trouble disassembling , refinishing , etc. If not I'll just hold off to the next rebarrel . If possible please feel free to recommend a smith as well.
