Yes, I think you are onto something there. When looking into the cut with good light there is clearly a bright spot worn through the blueing covering most of the right sidewall of the cut.

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.
