If that rubbed spot is on the barrel and not the receiver it is definitely a warrantee issue. The barrel needs to be tightened slightly(this will move the front sight also), or the extractor cut is not far enough to the right and need so be remachined.

If the wear spot is on the receiver it still may be a warrantee issue. The barrel extractor cut could be out of place for the same reasons as above but on the left side and tries to push the extractor to the right. In this case you might see wear on both sides. Further in on the barrel (left side) and outside on the right side of the barrel.

I bought a barreled receiver from one of the participants in this discussion so I could check things like this. I ran a probe down both sides of the slot and can feel about .002 or .003 mismatch in the one on hand. Sliding the extractor in there without the bolt there is about .005 clearance on the side of the extractor. That is pretty close tolerance. The boys at the armory did good work, but that tolerance makes it hard to duplicate 100+ years later doing only a few barrel jobs at a time. When I did the extractor cut on my sporter, I screwed the barrel in to normal torque then scribed a line on the barrel where the extractor should go and then made the extractor cut about .010 wider than required to allow for tightening error. The armory boys apparently did not have that luxury.

Unless you dropped the bolt and bent or otherwise damaged the extractor, it sounds like a warrantee issue. You might try sliding the loose extractor into the barrel/receiver slot for grins before you send it off. It is fairly easy to do.

The installer likely over tightened the barrel a couple of degrees or the notch and thread timing were slightly off.

Widening the notch slightly would be an easy fix with a file, if the barrel were off the action.

Very much Mavt's call. Frustrating that it wasn't done correctly and still isn't quite right.

IMHO - If it were mine, it is easily fixed with a little stone work on the right-side of the extractor claw.

I would not want to send it back to the installer and lose the use of a utility Krag for months.

(Oops, 'mavt' fixed it. Well done You! Give us a Range Report, soon).

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!   

I'll repeat it again at the risk of being annoying. I would send it back with a list of issues and request a new barrel, timed and aligned correctly that may require a new sight added since this one appears to be out of alignment with a poorly affixed barrel. You are shooting a barrel that is not 100% and can be considered dangerous. You should not have to be working on it yourself.

I do gun smithing myself but if I send a piece away for threading or repair or whatever, I expect it to be done correctly so I can trust shooting it with my life! My eyes, hands and life are important to me, as well as my treasured Krags!

If the request is not accepted easily, I would ask for a refund and find a more reputable gun smith.

If this is the case, please let us all know who this is so none of us will have him do any work for us. Reputations and quality of work, good and bad, should be shared!

Just my 2 cents. Do what you think is best. 

I feel like I'm getting to be an old snot like Dick, but at a much younger age. (Meant to be a compliment, Dick! You've taught me a lot!!)
