Final Update:
If you've followed my comments here, I had some minor problems with a DD barrel that cropped up during assembly of the upper. I considered pulling the whole thing apart, returning the barrel to the vendor, and starting over, but I thought that DD would like to see the situation as I did. I sent them the whole package (DD barrel, DD lite rail, VLTOR upper). DD paid for shipping.
Received the thing back last week, but did not have time to examine everything until yesterday.
DD did everything right for a customer that I could ask for. I now have a complete upper from those parts, assembled by them. The barrel appears to be new (i.e., different from the one I sent in). Pins are correctly inserted and no finish problem. Perfect. Now I just have to find time to shoot it. 
Of course, this is no surprise for a company of their caliber.
(Had to pun.) Just thought you might want to know.
