Yep. Purchased or made. Barrel blanks are unregulated lumps of metal. Drills are just tools. Traditional button rifling requires (I think) a slightly specialized lathe, but huge advances have been made fairly recently (past decade): one can etch rifling into a barrel blank with a 3d printed plug, flowing saltwater, and an electric current. Chamber cutters/reamers are also just tools.
