RH,
Here are a couple of pictures I snapped of my set-up last night. These are "medium" Mountain Tech rings btw. I tired the "low" rings and while they JUST cleared the barrel on the objective end, but the bolt handle was hitting the eye-piece on the back end. I suspect that is a function of the Talley two piece bases sitting considerably lower than most pic rails.
Maybe the eyepiece is smaller on the Nightforce than the LRHS and will allow you to run the lows. If so, I suspect scope caps will be out of the equation.
