The Weaver See-Thru Steel Lock Mounts come with two straps and an additional four screws to ensure they gives you the ultimate in gripping power. This mount is ideally suited for any 1-inch scope tube, as the ring diameter is 1 inch. You do not even need a base. The mount will position your scope naturally 7/8 inches above your receiver with its integral mount. The rings are made out of aluminum, which makes them lightweight and easy to use. There are thumbscrews attached, which make them easily detachable. All you need is your thumb.
