Hey - this has been covered before and I copied the information, so am sharing and hope it is of help:
Calculating Scope Ring Height
http://www.mil-rad.com/scope_ring_calculator
Ring Height Calculation
(Obj diameter/2)-((obj diameter-tube diameter)/2)+lens cap thickness + cant
(56/2) + ((56-34)/2)+3
28+11+3= 42 mm or 1.65 inches
you can honestly disregard the cant addition If you want but this gets you in the ballpark. The cant is there for for full pic rail calculations. If your rail is only over the receiver then you can usually disregard it. That changes it to around 1.5 inches which is very typical for a 56mm objective

Another way to do it is to stack pennies on you rail until your objtive clears the barrel then measure.

Thats what I did, took the pennies with and measured. Worked like a charm...
