The upper portion of the sight member is arrow-shaped and upwardly pointing when installed and includes an opaque or translucent layer on the upper portion of the otherwise transparent sighting member. The attaching means is also preferrably substantially transparent. Both sight member and attaching means have various embodiments, including lateral and vertical adjusting means for the sight member.
