I was thinking about this kind of.
I'm going to be using an ARC Barloc barrel tensioner soon. It will work with Savage pre-fit barrels but they also make a Remage version.
Like the bolt lugs in an ARC action, the Barloc has toroidal geometry so it can accommodate some misalignment which could be in the receiver face (If you were using a Barloc on a Remington that hasn't been trued up) or the barrel threads.
In my case I'm worried about buying Savage take off and pre-fit barrels only to find that I don't have enough barrel threads to screw it in to the receiver far enough because they were not designed to have a tensioner and a nut.
The solution would be to pay a very good Machinist to chuck up your barrel in a lathe, pick up the threads and extend them down the barrel. That's not easy, not cheap and might happen often with my luck.
My potential solution is to buy a standard threading die instead of try to thread on a lathe. The threads of the die will pick up the existing thread and with a Barloc, a bit of misalignment can be tolerated so no lathe required.
With a Remington barrel, you'll have to get the shoulder cut back so a lathe is required but you could use a threading die in the way I've described so potentially much less machining time.
This is probably not a good idea if you don't use a Barloc and it's a better idea for a Savage barrel where only a few threads would need to be cut and there would be no shoulder to deal with.
Any way, if the issue comes up, that's how I intend to handle it. A Chinese thread die might be $25 so it's a cheap solution for me. Making a Remage would be more expensive and then add a Barloc, I'm not sure if it makes $ense.
