OK, so here's the plan. I want to get a new barrel, have a brake installed, probably a baffled style brake so it will need to be indexed, shoot it a few times and have it sent off to have a nitride finish.

So the question is, if you take a barrel off will it go back on to exactly the same place every time, provided it's going on the same receiver? If I have the brake indexed and then take the barrel off will the barrel and brake go back on in the exact same spot after the nitride finish? From what I understand, once you nitride the barrel the work on that particular barrel is done. They are too hard to machine later and re-index the brake.
