Height - 0.974" - 24.7mm base to bottom of ring equates to maximum scope outer objective casing diameter of 74mm - Ideal for large objectives or where extra height is needed, for example, to clear high front or rear sights as well as diamater adding flip up caps etc.

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 required - the measure from base of mount to bottom of the ring - 24.7mm in this case

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 24.7mm

Example -

1. A 50mm objective lens scope (a Hawke Vantage 3-9x50 AO is about this) is measured and found to have an outer case measurement of 64mm.
2. 64 divided by 2 = 32
3. 1" scope so deduct 12.7mm = 19.3mm
4. So the mount must have a saddle measure (base of mount to bottom of the ring) greater than 19.3mm or else it will ground out on the rifle body.
5. As we have 24.7mm to play with here it will give 5.4mm clearance.
