Can anyone ID this Yankee Hill upper?

[Guest TankerHC]

I got this in a trade intending to sell it to help finance an R25 VTR purchase. The guy told me it was the 7810 Spector, but comparing it to YHM's website, it doesnt look like one. In fact is doesnt match any of their uppers. I do know it is definitely YHM, but the only markings on it are:

Small Keyhole just above the front part of the Forward Assist
YHM inside their Diamond emblem on all four sides of the delta ring assembly.
5.56 Nato 1/0 just behind the flash suppressor.

I really need to know which model because if it is a 7810, then Im looking at used private sale around $650. If it is one of the custom orders based on the 7810, then I could be looking at around 800.

It is definitely one of their Black Diamond models as you can see in the pic of the diamond fluted barrel.

Anyone know what this is?

Wrong flash hider, forearm, and gas block to be the 7810.

It just looks like an upper someone put together on their own with yankee hill parts, it doesn't look like it matches anything they have on their complete uppers. The closest thing it looks like is their 7830, but there are still some differences.

It is also possible that it is an upper that they no longer make, so it wouldn't be listed on their site. Edited December 9, 2012 by nysos
