I have two Baush & Lomb 10x Tacticals. They are original Baush & Lombs, not Bushnels.
One is mounted on a AR-50 (50 BMG). They have 145 MOA of up. I mounted it so I have access to all of the 145 MOA as "UP"
That is the most I have ever seen.
I have shot the rifle to 1,900 meters, but it will go to 2,900 meters if I can find the range.
Interesting. What type of base did you use to achieve this?
