There is often a bit more to fitting a muzzle brake
then many think.
First off, more home lathes or even gunsmith lathes will require the barrel to be pulled because the spindle bore inthe lathes are not large enough in diameter for the recoil lug on these rifles.
When I got my machines this was an issue I wanted to deal with properly. Since I was going to be working on large diameter 50 BMG barrels I orders a lathe that is much larger then you everyday gunsmithing lathe.
The perk is that all I have to to is strip the action or the trigger group and chuck it up in the lathe and roll with the live center on the tailstock supporting the muzzle for threading.
This cuts alot of time off the job and there is no need for a barrel vice either.
While fitting a muzzle brake is certainly not a problem for a machinest, for the average hobbiest, some brakes can be a little tricky. Especially if you have to index the brake to a certain location in relation to the rifle.
If you have lathe experience and access to a lathe, installing a brake is a simple matter. If you are not experienced, your project can result in a much shorter barrel to correct a mistake pretty quick.
