Had a friend who was buying cheap custom Mauser rifles and always telling me he was going to have a gun smith do this and that to them. I havent seen him for a few years, but I dont think he ever done anything with any of the Mausers he bought. He would let me look through his man cave while we drank beer, he had stuff leaned in corners, laying on the floor, etc. He had a couple of FN Mauser sporter actions that were brand new.
