That's a big question. There are a lot of things that must be done even swapping from one rem barrel to another.What all would i have to do to take my barrel off and put on a factory takeoff? Also its a. 308 boltface so what other calibers can i change too?
I hate take off barrels. I had one land in range. If they can't be cut off and installed fresh then I believe they are a waste of time and money. The interior finish on Remington barrels are a train wreck. Even as bad as they are if they are redone with modern techniques they can shoot pretty well.
