What are the advantages of BKL mounting systems?
1 - Installation is performed easily because there are few components to contend with. BKL uses the same #8-32 screws for both scope ring and base clamps. One 9/64 hex wrench tightens all.
2 - The inside diameter where the rings clamp together is radiused to prevent scope damage.
3 - BKLs clamping system self aligns as it tightens down on 3/8” and 11mm dovetails.
4 - No lapping required.

Do I have to center BKL scope mounts?
No. All of our products center up as the pressure from the clamping system pulls down as it clamps in.


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" diameter body tube diameter this would mean deducting 12.7mm and 15mm for scopes with a 30mm diameter body tube.

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 - the measure from base of mount to bottom of the ring - the saddle dimension that is stated 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. 

Example -

  1. A 1 inch tube scope has an outer case measurement of 60mm.
  2. 60 divided by 2 = 30
  3. 1 inch scope so deduct 12.7m = 17.3mm
  4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 17.3mm or else it will ground out on the rifle body.
  5. Here we have 21mm so will be 3.7mm clearance assuming it to be a standard flat base.

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.
