Calculating scope to rifle body clearance (NB)

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/25mm diameter body tube diameter this would mean deducting 12.5mm.

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 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 20mm for most picatinny/weaver bases or 14mm on a full length rail.

Example -

1. A 50mm objective lens scope is measured and found to have an outer case measurement of 64mm. Example Hawke Vantage 4-16x50 AO IR 14252
2. 64 divided by 2 = 32
3. 1" / 25mm tube scope so deduct 12.5mm = 19.5mm
4. So the mount must have a measure (bottom of mount to bottom of the ring) greater than 19.5mm or else it will ground out on the rifle body.

So in this case, as long as the base is raised (like in the picture below) then we have 20mm to use, so have a tight clearance of 0.5mm

Calculating your rifle scopes clearance in this way assumes the base is a regular raised from the gun body picatinny/weaver rail. Some rifles with high or adjustable cheek pieces may require higher scope mounts or risers so that your eye is in line with the rifle scope and your head is kept in an upright comfortable position.
