"The USMC uses nightforce, S&B, and tangent theta. Leupold is still around because of army contracts and people who don't care about Improvement in tech and settle for anything because they don't know any better. And on top of that most people aren't using their stuff enough to know their system the good or bad."
I assume you have military test data to support your claims about Leupold ?
May I assume that YOU own all scopes currently in use by our military and have run side by side optical tests using accepted mil-spec proceedures ?
Guess you missed this ?

The only optics experts I have found on the internet are on the SWFA sponsored site.
