Depending on what you're going to install this on I'd look to use a 20 MOA, or 30 MOA base, and as low as rings as you can install. Even a 15 or 20 MOA works better for anything less then 600-900/1000 yards since the scope reticle will be in the middle of the tube, that way you'll avoid having the erector pushed all the way down in the scope tube. Leupold makes a Long Range base with taper if you're wanting to use a Redfield Type base, I also like bases made by Murphy Precision.
