The scope ring includes a clamping mechanism, which provides an enhanced connection for Weaver and Picatinny style rails and rail bases. The scope ring includes a base member and a rail clamping member that bolt together at an angle and form the improved clamping mechanism. Tightening the fasteners draws the contact surfaces of the base member and the rail clamping member laterally inward against the sides of the rail base and vertically downward against the top of the rail base.
