Abstract: A device and method for stabilizing a rifle scope that employs a pocket cut in the bottom of a scope base (picatinny rail) that precisely mates with a key formed on the top of a recoil lug, such that when the scope base is attached to the rifle's action receiver and mated with the lug's key, the lug holds the barrel and the scope base locked in tandem so that they move exactly together during recoil events or any vibrations experienced by the rifle.
