[Catskinner]

I just received my rifle back from Smith. I wanted to have the barrel threaded and they sent my rifle back with a new barrel plus my old plain one.I don't know what to ask for it.I am thinking about $50.00 plus shipping?It has only about 300 rounds thru it before I returned the rifle for warrenty work. Thanks Ron
