Abstract
A reinforced scope ring can be used singly or in pairs and can be affixed to a Weaver or Picatinny rail. The reinforced scope ring includes a base, a removable jaw attached to the base by first and second transverse threaded fasteners and first and second knurled nuts, first and second semi-cylindrical split rings and a substantially semi-cylindrical top ring member which is removably attached to the base. The base includes first and second apertures aligned perpendicular to the scope axis and spaced apart by approximately 0.80 inches to engage alternate transverse notches in the Picatinny rail. The first and second transverse threaded fasteners have an elongate body with a substantially rectangular cross section to provide transverse lug surfaces tending to fill the transverse notches in the Picatinny rail and engage notch surfaces in the left and right rail members.
