Several years ago I built a .470 dr from a CZ Bobwite 12 Guage. A gunsmith threaded and joined the barrels to the mono block and he welded and fit the extractor so I basically just regulated and finished it. I have a couple hundred rounds through it and it still locks up tight. The smith and I proofed it with heavy loads but never sent it over seas to proof. Any legal or moral concerns with me selling it now?
