Can't help w/the exact manufacurer of the raw forging for the upper, but it sounds like a Vietnam era M16A1 barrel and upper. My best guess is that it was put on a Colt built M16. The marks on the reciever forging are contractor IDs that are found on Colt guns, and the barrel markings are consistent with the way Colt marked its barrels.
