Re: Measuring the scope hight
Canderson has it right.
A quick way, that is nearly as accurate is to slide the bolt back until it is directly under the scope bell. Measure from the bottom of the bolt to the top of the scope bell (be careful of any slop you have in the bolt). Then subtract half the bolt diameter and half the scope objective diameter. Or just eyeball from the center of each with your calipers.
It sounds a little 'shade tree', but it is easy and gives nearly identical measurements to other methods.
If some is good and more is better, then too much is just right.
