Yes, these will work on your Winchester Model 70. Just verify the tube diameter on your Leupold VX-3i, as there are a couple variants of the 4.5-14 and they have both 1" and 30mm tube diameters. From there, you should be able to go with medium height rings in the tube diameter that matches your scope.
