I did send an email to the service that did this replacement but also saw they are closed until next week so may not respond until then.  This is my first (and last) barrel replacement. What is involved to realign the barrel? Strip down the receiver again and use of a receiver and barrel wrench? Does this affect the blueing? Won't the headspace now be a bit long? The Criterion barrel has an extra ring of material around the chamber opening that is used to fine tune headspace that appears to have already been removed.

As mentioned previously this has has already been returned twice for issues before the fail to chamber problem. The more required to rectify this the more I want to avoid sending it back and look at other options like a front sight base for dovetailed sights aligned correctly to the bore even if it requires cutting and crowning. Financial adjustments have already been made on this job so the only leverage I have at this point is reputation and the need to keep my sanity after a year of this!
