I have a barrelled action that is no-good. The barrel is completely rotted out. The action has also been stripped of all major parts. Bolt is missing etc. I was hoping to unscrew the barrel and keep the receiver as a shelf ornament. Does anyone know how this is done? Or should i just take it to a gun smith? I dont care if either part works again as long as i can clean it, re blue it and make an ornament.
