Calculating scope to rifle body clearance

The way you calculate the clearance is by halving the overall OUTSIDE diameter of your rifle scopes objective lens and then deducting half the rifle scopes body tube diameter.

For scopes with a 1 inch diameter body tube this means deducting 12.7mm.

Note we say OUTSIDE diameter - this means NOT the lens diameter, you need to measure the whole outer casing diameter.

The result gives you the minimum "saddle" dimension required - the measure from base of mount to bottom of the ring - the 'A' dimension that is shown above (19mm)

The amount the saddle dimension is greater than the figure you have calculated is the amount of clearance your scopes objective will be clear of your rifles body.  The saddle on these mounts is 19mm

Worked Example -

1. A scope has an outer case measurement of 56mm.
2. 56 divided by 2 = 28.
3. 28 minus 12.7 = 15.3mm
4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 15.3mm or else it will ground out on the rifle body.
5. So in this case with 19mm we have good but not too excessive room. 

Keep in mind that flip up lens caps may add 2mm or so.
