A system for mounting optical sights is disclosed employing an elongated mounting base for attaching a sighting device to a firearm having a dovetail portion extending in the direction of elongation to form a pair of spaced apart sight clamp accepting grooves which extend parallel to one another in the direction of elongation. First and second recoil lugs extending away from the dovetail portion in opposite directions are also disclosed with the first lug engaging the firearm to prevent movement of the base relative to the firearm when the firearm is discharged and the second lug engaging the sighting device to similarly prevent movement of the sighting device relative to the base when the firearm is discharged. The dovetail portion slidably accepts complementarily contoured portions of the sighting device which may include a pair of spaced apart clamping legs for slidably engaging the grooves and tightening means between the legs to draw those legs toward each other to grip the base.
