Abstract:
In the method of adjustably positioning and attaching coaxially spaced mounting rings in axial alignment on a firearm for attachment of an optical gun sight coaxially within said mounting rings, the firearm having a receiver and a barrel and with the barrel comprising a firearm bore with a breech at one end and a muzzle at the opposed end, said method comprising:(a) coupling a bore sighting assembly onto said firearm at said breech end for directing a coherent beam of monochromatic light axially through said firearm bore and onto a remote target; (b) mounting a hollow cylindrical coherent light source retainer means within said mounting rings; (c) positioning a second source of coherent light within the hollow core of said coherent light source retainer means with said second source of coherent light being retained within a light source retaining housing of cylindrical configuration, and with the beam of coherent light from said second source being emitted coaxially with the axis of said hollow core; (d) said second coherent light source retainer means including dual eccentric sleeve means telescopically received within said hollow core, and with the axes of said dual eccentric sleeve means being disposed parallelly to the axis of said hollow core; (e) directing said first and second coherent light beams onto said remote target; and (f) positionably adjusting said gun sight mounting means upon said firearm until the axes of said first and second coherent light beams are arranged along a common vertical plane.
