Hey guys, newbie to the board here. I'm building a Remington 700 heavy barrel with a Leupold 4.5-14x50 M5 FFP on it. The problem is, I'm in Iraq at the moment trying to order rings and since I don't have my hands on it to measure, I'm not positive if I can get away with a medium height ring or if I'll have to go with a high. Anyone have a similar setup that can give me a hand?
