BKL-254D7-MB BKL Technologies 1" Drop Compensated Cantilever Dovetail Scope Mount

Why choose the BKL-254D7-MB Scope Mount?

The BKL-254D7-MB is a 4-inch drop compensated cantilever scope mount designed for rifles with standard 3/8-inch or 11mm dovetail rails. Its one-piece design combines a 1.65-inch clamping section with a forward cantilever extension, while the drop-compensated configuration provides additional mounting height for scope positioning and clearance. The cantilever design also gives you more flexibility when positioning a scope for proper eye relief.

The BKL-254D7-MB accepts 1-inch scope tubes and positions the scope tube 0.974 inches above the mounting surface. Its 4-inch overall length provides additional forward mounting reach compared with the shorter BKL-253-MB, while the 1.65-inch clamping section maintains a compact connection to the rifle's dovetail rail.
