I have a question on ring height for an FN SPR A1 rifle. I am wanting to mount a Sightron 8x32 scope with a 56mm objective head (I believe 2.56 inch in diameter) and use Leupold Mark IV high rings - my question is will it clear the barrel? I checked Leupold website and they state Mark IV high rings measure 1.06. I'm not certain of the math involved to determine fit?
Thanks
