BKL 1 Piece 3/8"-11mm Dovetail Riser

This riser works with either 3/8" (9mm) or 11mm dovetails or scope rails. It.is 1 5/8" inch long and raises a BKL 253 or 254 Cantilevered mount an additional .68" above the scope rail or dovetail. It is designed to work great with the BKL 253 and 254 Cantilevered Mounts which have a base that is also 1 5/8" long. So for the shooter using these mounts that needs just a bit more height for his scope.
