Patent ID: 7562485

Claim:
Apparatus comprising a. a male dovetail rail, b. an auxiliary device, and c. coupling structure integrated with the auxiliary device in a manner that enables the auxiliary device to be selectively coupled with the male dovetail rail or uncoupled from the male dovetail rail; d. the coupling structure comprising a side bar and a flex bar in facing but spaced relationship, a cam lever that is pivotal relative to the flex bar, and a recoil locking cross bolt connected with the side bar, flex bar and cam lever in a manner such that (i) pivotal movement of the cam lever in one direction initiates a bend in the flex bar, draws the side bar towards the dovetail rail, and establishes and maintains mating surfaces between the side bar and dovetail rail, enabling the auxiliary device to be coupled to the male dovetail rail, and (ii) pivotal movement of the lever in an opposite direction initiates a slight bend in the flex bar, moves the side bar away from the dovetail rail, enabling the auxiliary sight device to be uncoupled from the male dovetail rail.
