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 30mm diameter body tube this means deducting 15mm.

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

Worked Example -

  1. A scope has an outer case measurement of 64mm.
  2. 64 divided by 2 = 32
  3. 32 minus 15 = 17mm
  4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 17mm or else it will ground out on the rifle body.
  5. So in this example, mounts have 20mm so there will be 3mm clearance all other factors being equal.

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

Calculating your rifle scopes clearance assumes that:

  • Your base is not raised above or below your rifles barrel
  • A raised Weaver/Picatinny base may add height
