I need some help... I've got a RA XCR and will be mounting a Leupold MK4 1.5-5 with 30mm tube on it. I want to buy one of the QD ring setups (Vortex, LaRue, Burris P.E.P.R., etc) and would like to keep the BUIS on the gun. I want to know what mount/ring height I will need for the ocular lense to clear the stock MI sights? I'm on a severe black rifle kick, so pics of your scope/mount setup would be very, very welcome!
