[QUOTE="Senderofan, post: 1081856, member: 13831"] That will depend on what scope base you go with....IMHO. If you can get the thickness of that.....it might help you calculate what ring height you need without going too high. There is a fair amount of variability with talking about the "Highest rings". This is a list of NightForce ring heights, I picked them since they have a nice list with different options in the "High" category: Height: Low: 0.885" Medium: 1.00" High: 1.125" Intermediate High: 1.265" Extra High: 1.375" Extreme High: 1.50" So, if you have the scope and can measure the outside of the front objective..... I've seen a fair amount say an average 56mm measures 60mm on the outside. You are working with half of that....anything above 30mm will get you space above the barrel. The NightForce "High" rings..1.125" will get you 28.575mm above the scope base.... ( 1.125" x 25.4mm ( which is an inch in mm's)) My Farrell bases add at least 1/4" to the height of my scope...or 6.35mm. So in that scenario...add it all up and you'd have 5mm of space by itself............. or 3mm's ( about 1/8th of an inch) with a Butler Creek front cover on the front of that scope( Butler Creeks add 2mm around the front objective.) If you didn't take the time to measure and calculate....and got the 1.5" rings....you'd probably have a ton of space and might have issues with site picture unless you build up the cheekpiece. Of course the Intermediate High rings would probably give you space to spare and not have to think about how thick your base is. Just some ramblings from an old fart varmint hunter. Best of Luck, Wayne If you go with a canted base(s).....you might lose a little height of the base due to the scope being tilted towards the barrel. [/QUOTE]
