The BKL-566-MB provides a compact way to add a Weaver/Picatinny mounting platform to a rifle with a 3/8-inch or 11mm dovetail receiver. Its 1-inch length is useful when a full-length adapter is unnecessary or when you want to keep the mounting footprint short. The adapter adds 0.69 inches above the original dovetail and provides a 0.76-inch overall height. BKL specifically describes the 566 as ideal for mounting red-dot sights, making it a practical choice for rimfire rifles and airguns that use rail-mounted optics or accessories.
The BKL-566-MB is designed for rifles and airguns with 3/8-inch or 11mm dovetail mounting rails. BKL's clamping system is designed to fit both rail widths and uses its self-aligning mounting system to center the adapter on the dovetail. The resulting Weaver/Picatinny platform allows compatible red-dot sights, scope mounts, and accessories to be installed on a grooved receiver.
The BKL-566-MB is the compact 1-inch option in BKL's 500 Series. The BKL-558-MB provides a longer 4-inch mounting platform in a rimfire adapter configuration, while the BKL-554-MB uses a 4-inch cantilever design with a shorter clamping section for additional forward positioning. The BKL-568-MB provides a full 4-inch mounting and clamping length for applications where a longer adapter is preferred.
