Quick Detach and Lock

Scope size fitting considerations:

Typically this mount is suitable for upto 50mm lens scopes. The Leapers stated measure is 60mm but that refers to the OUTER diameter of the lens where you must take the lens casing and, if you have them, things like flip up caps into account. If in doubt go up a size to high profile or ask me if unsure.

In addition if you have a rifle with a raised base where the scope is raised above the body further than normal then this may mean that a lower profile mount will work well and might be better than a higher model.


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 'C' dimension that is shown above.

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 -

Worked Example -

  1. A scope has an outer case measurement of 58mm.
  2. 58 divided by 2 = 29.
  3. 29 minus 15 = 14mm
  4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 14mm or else it will ground out on the rifle body.

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.
