In combination with a firearm having a barrel with front and rear sights, a telescopic sight of one diameter spaced above and parallel to the barrel. An elongated land is secured upon the barrel with opposed elongated outwardly opening V-slots therein. A pair of longitudinally spaced reversible telescopic sight mounts supportably engage the telescopic sight and are adjustably secured to the land. Each sight mount includes a pair of opposed symmetrical scope brackets. Each bracket comprises an arcuate top wall with a tapered longitudinal edge and with an internal semi-circular face of a first radius; an arcuate bottom wall with a tapered longitudinal edge and an internal semicircular face of a second radius, and a centrally apertured abutment interconnecting the top and bottom walls. Opposed pairs of top walls receive therebetween opposed sides of the telescopic sight and the edges of the bottom walls project into the grooves on opposite sides of the land. A fastener interconnects the abutments of a pair of brackets for gripping the sight mount between the top walls and gripping the land between the bottom walls. The brackets are reversbile end-to-end with the bottom walls adapted to retainingly engage a telescopic sight of a second diameter and with the edges of the top walls retainingly engaging the land.
