Looking for a scope on a pretty tight budget for my Ruger American. Debating between vortex crossfire II, diamondback, and Leupold lower end scopes. Looked through vortex and leupold and really could not tell the difference in clarity, price was close, but could save decent cash going with the Vortex. Just never heard of them. The nikon that was priced the same was no where near in clarity to these other 2 brands. Anyone have any experience with Vortex?
