One of the slickest, smoothest ring/base combinations ever. The ring is split, vertically, at the mounting post with absolutely no screws or even any "lumps"; just wrap it around the scope, squeeze together and slip the post into the S&K base. Dual opposed, conical screws serve as ring clamp screws, and also provide windage and alignment adjustments. Mount rings on the base for low mount applications; add Riser Blocks for more height. Sculptured Mounts available separately.
