Fitting guidelines and clearance considerations

These mounts are for 9-11mm dovetail rails as typically found on air rifles and rimfire.

They are for 30mm scope tubes

They are "high" profile with 17mm measured from base of mount to base of ring (Saddle) - This is a critical dimension when calculating clearance over the rifle body.

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 case and then deducting half the rifle scopes body tube diameter.

For scopes with a 30mm diameter body tube diameter 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 17mm

Example -

1. A 50mm objective lens scope is measured and found to have an outer case measurement of 57mm.
2. 57 divided by 2 = 28.5
3. 30mm scope so deduct 15 = 13.5
4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 13.5mm or else it will ground out on the rifle body.
5. So with 17mm there will be 2.5mm clearance on a flat base, very nice.

Calculating your rifle scopes clearance in this way does assume your dovetail or base is not raised above or below your rifles barrel. Note 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.
