Anyone hear of this site or their parts?

Never heard of it but it looks like another one that I have only heard bad experiences from.

Advertising Armalite-compatible AR10 complete uppers for $379 with the barrel?

Sounds too good to be true, and I personally can't take them seriously. The wording and descriptions, as well as website coloring, background, and layout is almost identical to the other company.

If I ordered one of these uppers, I wouldn't expect the least degree of quality, if a product even arrived. It just doesn't pass the smell test for those of us who have been tracking AR10 parts pricing for the past 10 years. A barrel alone will cost what they are advertising a barreled upper for, complete with gas block, handguard assembly, and muzzle device. When I blow up the picture, I see an image where the brass deflector is absent from the upper, which is advertised as "billet".

Sounds like we need a full report from someone that has actually ordered from this company, but I see nothing but red flags. There are stripped billet uppers on the cheap end that go for $299 in the AR10 market.
 
Run a search...they've been discussed at length on here, BARFCOM, M4C, etc., etc., before. Black Thorne, Blackthorn, Hesse, etc., etc....its all the same.

I'll give you the short, SHORT version...

RUN, DO NOT WALK, THE @#$% AWAY!! They are 100% shite in terms of quality, reliability, value for your hard-earned dollar, etc. and share one of the single worst reputations in the industry for the piss poor garbage they put out.
