With Leupold Quick Release steel bases you can mount a scope, zero it, remove it, reattach it and remain nearly dead-on with your original point of impact. The key is precise machining of the patented lever mechanism. Turning the lever forward engages the base of the ring, pulling the ring down and forward, locking it into its "zero" position.These are NOT standard bases. They use a cam-lock to hold the rings to the base so the scope and rings can be removed quickly and easily. These bases must use Leupold Quick Release rings, but NOT Leupold Quick Release Weaver rings. The Weaver base is different from this one.
