BKL Model 463s for 1" scope tubes are a heavy duty double strap set of rings designed for the target shooter who is looking for more dovetail clamping surface.
Designed to fit 14mm (0.55") dovetail rails, not many mounts that fit this width. 14mm is quite an unusual dovetail width, if unsure check that you have it as most airguns and rimfire bases are between 9-11mm. The 14mm are also good for those tricky "just over 13mm" dovetails often found on older airguns, BSA and HWs
The
BKL400 scope mount ring models are ideal for the BSA Maxigrip rail as
on the BSA Lightning, a base rail that is notoriously hard to get proper
mount rings for!
13mm BSAs rings, Sportsmatch etc fit - just - but cause crossover and zero issues. The BKLs at 14mm are a spot on fit.
If
you have been having a headache trying to fit mount rings for a BSA
Maxigrip base a BKL 400 rifle scope mount ring pair is what you need -
and BKLs are brilliant quality too.
- Scope tube diameter: 1" (25mm)
- Overall Length: 1" (25mm)
- Clamp Length: 1" (25mm)
- Ring Width: 1" (25mm)
- Weight: 4.4 oz. (123g)
Bottom of Mount to bottom of Scope Tube: 0.774” - 19.5mm - i.e., they are a high profile mount best suited for scopes with 40-56mm objective lens - Also see clearance guide below
BKL - A superior mount ring
Strong One-Piece Clamping Base allows easy mounting of rifle or pistol scopes.
Patented Auto-Centering technology solves the problems created by varying mounting rail widths.
Clamping Legs move equally as the clamping screws are tightened keeping the scope centered on the rail.
Oversize mounting rails? No problem. Clamping screws can be switched to BKL's unique Spreader Holes to evenly push the clamping legs apart allowing the mount base to slide onto the dovetail.
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 - 19.5mm 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.
Example -
- A Nikko Nighteater 1"
4-16x44 scope has an outer case measurement of 51mm.
- 51 divided by 2 =
25.5.
- 1" scope so deduct
12.7mm = 12.8mm
- So the mount must have
a saddle measure (base of mount to bottom of the ring) greater than 12.8mm 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.
BKL mounts are manufactured from aircraft-grade aluminum alloy on state of the art machinery in Texas.
