I received a bent Leupold base, from another company. Tried this one as a suggestion, and awesome fit.
Minimal internal windage and elevation adjustments for boresight. Looks great with my VX-3 mounted inside...1971 Brwng BAR Grade 2.
Pros: Easy Install, Looks great, uses all 4 screws for base!
Cons: None at this time
