Abstract
A detachable mounting post to permit a user to remove or reattach a telescopic sight without having to realign the sight with the rifle. The mounting post includes an axial displaceable stirrup that can be moved along the axis of a mounting post by the coaction of a threaded anvil having cam surfaces that engage mating cam surfaces on the stirrup as a user rotates a longitudinally fixedly mounted screw to pull or push the anvil in a direction perpendicular to the axis of the mounting post which causes balls located in the mounting post to center the mounting post both vertically and concentrically within a mounting socket located in a mounting block on a rifle.
