Sounds like he gave the retailer an opportunity to me, or did you miss that, he can do what he wants with it rebarrel it or whatever he likes he chose to take it to his smith and have the work done....lots of mass produced guns end up at smiths for whatever reason from time to time as mistakes happen quite often when an operation gets to a certain size. It seems to be a real hang up on cooper in general, if they are your system of choice great, they just might not be the choice of others....I think this post was more to point out a chambering problem and not what the warranty of the manufacturer is or was or the dealer for that matter or who the smith that did the repairs...I am sure if it was a problem worth the effort it would have made it to cooper rifles.
