Telescopic sight mounting

Claim 1

In combination with a firearm having an iron sight mounted on an elongated barrel: a telescopic sight; base plate means mounted on the firearm, said base plate means having V-shaped longitudinal, parallel ridges along opposite sides thereof; a pair of longitudinally spaced supports mounted on the base plate means, each support including a body having a semicylindrical wall for receiving the telescopic sight, and a pair of spaced side walls having upper edges integrally connected to the convex side of the semi-cylindrical wall, and lower edges with opposed V-shaped grooves mated with ridges of the base plate means, such that the semi-cylindrical wall is spaced above the base plate means to permit the user to view the iron sight along a line of sight between the base plate means and the telescopic sight; a fastener connected to both side walls of each support adjacent the base plate means, the fastener being operative to move one of said side walls toward the other side wall to releasably clamp the base plate means between the lower edges of the side walls; a half ring for each support, each half ring having its midsection mounted on the telescopic sight adjacent the support, the means for connecting opposite sides of each half ring to opposite sides of each semi-cylindrical wall to prevent movement of the telescopic sight with respect to the supports.
