Mr. Self's mount changes all this. It's an updated version of a design that's been around for over a century. The VGM fits on Weaver or Picatinny bases, takes rings for same, and lets you use whatever scope you like, because the Gantry Mount tilts upward at the rear, giving you your compensation for distance, and locks in place with a hardened steel pin. There are five pin settings, and what you do is find out, by shooting (or with a dial indicator), which pin setting works at which range. No more relying on small fragile parts; no need to spend a fortune on a fancy scope. The VGM is $350, and $400 if you want a dial indicator with it.
