Eric, Not an answer to your question, but I have a Burris Black Diamond and couldn't be happier.... Also when I called the Burris Customer Service to get advice on the rings to mount the scope to my rifle, they were excellent in getting me the correct information..
I do know that, at one time, Bausch & Lomb used to make lenses here in the U.S. and were excellent in quality.. . I have a pair of binoculars that were made for the Navy by them in 1943 that I've had for at least 40 years and they are as good, if not better, than many on the market today..
