I have four M70's in long action, including one rechambered to the Lott cartridge.
For the first, I bought the Leopold mounts. They fit a bit less that optimum for a Vx-II 2.5-8. About one mm of space available to fit fore and aft. Luckily, it was just right for my view, etc. The front base hangs over the action cutout by a bit. No function problems though.
For the others, I bought Talley. Two detachable and one fixed, but not the one-piece I saw referenced here. They are probably the best, but not all scopes will fit due to the spacing. I can vouch that the Conquest 3-9x40's do, with room to spare, as well as the VX-III 3.5-10's. Your Vx-II probably has available mounting room similar to the latter, but might want to double check.
