On the LRP I plan to run a Vortex HDII in vortex precision rings. As for a base it will either be a pt&g, EGW, or Warne (steel). The link I posted above will help you figure out clearance. The butler creek caps for the PST are 2mm thick, like I said before it's the scope I run on my savage 10ba. I use it for long range practical tactical competition. We shoot 100 to 900 yards pretty regularly. That scope sits in vortex medium precision rings on an EGW base.

I am glad you are having such success with your LRP I hope mine performed as well.
