I'm thinking about buying a .280 Rem and having it modified into a .280 AI. Other than reaming out the chamber, are there any modifications that will be required to make this a reliable, accurate rifle? I realize "accurate" is relative and if the gun wasn't accurate before, it won't be accurate after. But I'm just considering stuff like, do the magazine rails need to be altered, will the same rifling twist rate work ok, etc. I can't imagine much would need to be done, but I wanted to get some opinions before I start the project. Thanks.
