BKL-554-MB 4-inch dovetail-to-Weaver/Picatinny cantilever mount converts a rifle's dovetail receiver into a Weaver/Picatinny mounting platform while providing additional forward scope positioning. The 4-inch mount uses a 1.65-inch clamping length and cantilever design to extend the optic forward from the receiver. It provides a 0.76-inch overall height and adds approximately 0.69 inches above the original dovetail rail. The BKL-554-MB is a practical choice for rimfire rifles and airguns when a longer rail-style mounting surface and additional scope positioning are needed.

The BKL-554-MB is designed for shooters who want to add a Weaver/Picatinny mounting platform to a rifle with a dovetail receiver while gaining additional forward scope positioning. Its 4-inch cantilever design extends the mounting surface forward from the 1.65-inch clamping area, giving greater flexibility for positioning compatible optics and accessories. The mount raises the mounting surface approximately 0.69 inches above the original dovetail rail and provides a 0.76-inch overall height. This makes the BKL-554-MB useful when a direct dovetail mount does not provide enough scope positioning or when a rail-style optic mounting system is preferred.
The BKL-554-MB is designed for rifles with compatible dovetail receiver rails, particularly rimfire rifles and airguns. BKL's mounting system is designed to fit both 11mm and 3/8-inch dovetails, while the 500 Series provides Weaver/Picatinny adapter mounts for these rifles. The cantilever configuration is useful when additional forward positioning is needed beyond what the rifle's original dovetail rail allows.
The BKL-554-MB combines a 4-inch rail surface with a cantilever design and 1.65-inch clamping length, making it the choice when additional forward scope positioning is needed. The BKL-558-MB is also 4 inches long but uses a different rimfire adapter configuration. The compact BKL-566-MB provides a 1-inch mounting surface when a shorter adapter is preferred, while the BKL-568-MB provides a full 4-inch clamping length without the 554's cantilever configuration.
