An apparatus including a rigid base having a first portion, typically the top, that is configured to receive and support an auxiliary sighting aid for a firearm (e.g., a rifle, shotgun or pistol). A typical configuration may be a standard dovetail shape that is sized to receive scope rings of the Weaver type. The firearm must have an accessible aperture, but it need not be integral with the firearm\s original structure; an adaptor can be attached to the firearm\s original structure so as to create a structural extension which contains the necessary aperture. The rigid base also has an exterior that fosters the correct orientation of the auxiliary sighting aid with respect to the firearm\s longitudinal bore. A post having a generally smooth exterior is carried by the base and extends outwardly therefrom for a distance which is sufficient so that the distal end of the post may be inserted into the aperture on the firearm. A hook is provided at the distal end of the post so that it may be pushed under a portion of the lip surrounding the aperture. By pulling upward on a properly placed hook, it can be caused to bear tightly against the lower surface of the lip in order to rigidly secure the post (and the rigid base) to the firearm. One way of causing the post to rise or descent in a smooth bore in the base is to provide threads in the top of the post, and then provide a threaded nut for engaging the post. Ideally, a permanently-captured, threaded nut is located near the top of the base, so that it is readily engageable by the digits of one hand－which may be the same hand that is holding (e.g. cradling) the auxiliary sighting aid. This permits one-handed installation or removal of a scope or the like on a firearm.

An apparatus for installing an auxiliary sighting aid such as an optical scope onto a firearm such as a rifle, shotgun or pistol, said firearm having a longitudinal bore and having a structural part with an aperture that extends therethrough, and that portion of the structural part which immediately surrounds the aperture constituting a lip, comprising: (a) a base having a first portion that is configured to receive and support an auxiliary sighting aid for a firearm; (b) means for orienting the base with respect to the firearm so that an auxiliary sighting aid which is attached to the base will be generally aligned with the firearm\s longitudinal bore; (c) means for selectively connecting the base to the firearm, including a post extending outwardly from the base and the post having a longitudinal axis and a generally smooth exterior, said post having a size and shape which permits it to be inserted into an aperture on the structural part of the firearm, and the post also having a slot which extends transversely inward from one side of the post, and the slot having a width that is great enough to envelop the lip of the structural part when the post is inserted into the aperture and then moved sideways after the slot has been aligned with the lip; and (d) means for selectively and rigidly securing the post in the aperture, including means for moving the post into physical contact with the structural part after the slot has been aligned with the lip and the post has been moved sideways by a short distance that is sufficient to place a portion of the post under the lip, said base being rigidly fixed to the firearm when the post is rigidly secured in the aperture, whereby the combination of an auxiliary sighting aid and a base that is affixed to the auxiliary sighting aid may be selectively installed and removed from a firearm as a unit by merely securing the post in the aperture.
