Okay, I've got a new 4.5-27x56 Razor II on pre-order and I wanted to go ahead and have a mount ready for it when it gets here. Here's my issue, The new razors lose about 3 mils of total elevation over the Gen 1's (which is what I have now). I would like to get that elevation back, externally. Ideally I want 30 MOA of external cant. But the cheaper option would be to get a 20 MOA Spuhr mount to go with the 20 MOA base I already have to give me 40 MOA total. Will I be able to get this to zero at 100 and still not have any distortion when looking through the glass? Or my other and more expensive option would be to buy a 0 MOA rail and 30 MOA Spuhr mount. Which option would perform better?
