Just emailed my local gun store just to check up on availability of uppers. They told me they didnt have any factory built uppers, but they had some custom uppers they built in house. Now i've used them many times and I trust them, but I fear they are stretching the price tag a tad bit on this one. Their "custom" upper consists of a "Daniel Defense upper with an FNH barrel, Yankee HIll rail and mil spec parts" for $700. To me, this seems a steep since the internals are probably some random "mil spec" BCG, charging handle, etc. Seem like a fair price?
