Hi, I'm trying to help my dad with a decision on what scope to get. He likes the Nightforce NXS 8-32, but the Leupold Mark 4 LR/T 8-25 is a much better price. I've read about the older Leupolds having canted reticles, and other possible problems, while no one ever says anything about the Nightforce. Has anyone had bad problems with the Mark 4 8-25? Thanks.
