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.

BKL customer user review on related BKL-300 mount
I mounted my Vortex Viper, 6.5-20 onto relatively new LH CZ 452 American, .22LR,  for SB Met. Silhouette.   Scope alignment at 40 meters for 0 setting at this first distance,  needed very little adjustment with new rings. I really like the design of the ring plus how solid it is and aluminum.  I will be another person praising BKL on several forums. I plan to buy your BKL-200 for my granddaughters Savage youth .22LR.  rifle.
