I have a remington 700 and want to put a US Optics base that is .625in tall on it. The scope I am putting on it is a Vortex Viper PST 6-24x50 with the outter dimension of the objective is 2.26in. Plus I will need prolly 3mm(not sure about inches) for my lens covers. I keep seeing all these formulas but when I do them it just doesnt seem right. I want it sitting as low as possible with just a little bit of clearance and dont want to get the wrong ring height. Thanks!
