There should not be pits in that barrel, nor should there be noticeable machining rings. Are you able to feel those pits and rings, maybe with a pick of some kind, or just see them?
Have you tried some additional Hoppe's with a brush in that area, from the muzzle, just to make sure it's not some surface "gunk"?
I've seen some really bad looking barrels throw great patterns, so it may not effect performance but it does effect value.
Since it's such a new gun, Remington would probably replace it.
