Just in case someone else is looking.
Leupold makes them in their Backcountry line for either their base or picatinny\Weaver.
Then they have the Mark 4 picatinny also.
I grabbed a set of Backcountry picatinny for my Mark 5, 5-25 and they are perfect on a standard set of Weaver bases on my Bergara B14 ridge. They would get tight with a 20 moa base or larger barrel contour though, which means stepping up to the mark 4 line to get extra height.
