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 Our clamping system self aligns as it tightens down on 3/8” and 11mm dovetails.
#4 No lapping required.
How tall are BKL mounts and risers?
From the bottom of the foot to the base of a scope tube our 200 Series mounts are .774" tall for regular height or .974" tall for high versions, and our 300 Series mounts are .989" tall. BKL Risers will add .67" to the mounting height.
Will BKL scope mounts stay zeroed if I remove the mount and install it again?
No. However you can maintain a high level of repeatability by keeping the scope tube attached to the scope mount and loosening the base clamp just enough to slide the setup off of the receiver. This will usually keep adjustment down to one or two clicks.
How do I know when the scope tube is properly clamped?
When the oval shape of the ring becomes a circle around the scope tube and no gap is seen between inside diameter of the ring and the outside diameter of the scope tube. Important: Do not close the gap between the edges of the ring (the flat surfaces where the screws are) as this might crush your scope tube! Please refer to our technical data sheet for more information.
Do BKL scope mounts require lapping?
No. All BKL mounts are designed to eliminate the need for lapping. Stress relief slots in the base clamp and the thickness of the top clamps allow the mount to form around the scope tube rather than distort its roundness and alignment.
