Again, get out a ruler, measure the current scope, and compare the total tube length and the tube on either side of the turret, and compare it to the spec drawings.
The VX-3 2.5-8 and 1.75-6 have the longest eye relief and the 1.75-6 has a long tube.
Call Talley about ring height. My pre-64 needed med rings for a 3-9X40 VX-II.
