[QUOTE="milanuk, post: 212248, member: 376"] If you want to be particular... take a set of calipers then: measure the scope tube diameter, measure the receiver diameter, measure from top of tube to bottom of receiver, subtract 1/2 tube diameter and 1/2 receiver diameter = centerline of scope above centerline of bore. Then you have people who get all twitterpated over the difference in height between the fore and aft ends of the tube when using a 20 moa canted base, and try averaging the two measurements... Close enough: Take a ruler, and eyeball it from the middle of the scope tube to the middle of the receiver (hint: the gas port on the side of the receiver just above the stock is a good reference), and get it w/i 1/4". If you are bored, plug in different numbers (1.5, 2, 2.5) and see how much it matters (not much). 'Close enough' works pretty darned well. YMMV, Monte [/QUOTE]
