I have a Remington 788, one piece Redfield or Leupold base. Standard Leupold rings lined up nice vertically, used ring alignment bars. I found I needed extended rings to bring them closer together as the scope I bought(VX-2 4-12x40 AO) has a very short tube. I tried two different sets of Leopold extension rings and the front extended twist in ring is higher than rear ring on both sets. Looks too high to lap out, what do I do?
