As illustrated the invention illustrated and described is typical in Figs. 3 and 4, the reticule consists essentially and representative only, the 1nvention being susof a ring comprising a lower half iii of an exceptible to many modifications, all falling within the scope of the appended claims.

What is claimed is:

1. A reticule for a firearms sight comprising a ring having two portions of differing exterior diameters, and manipulative means associated with said ring, there being a continuous circular groove in said ring adapted for engagement by a reticule retaining member.

2. In a firearms sight, in combination, a cylindrical hood having therein a semi-cylindrical transverse slot adapted to receive and support a reticule, a reticule adapted for insertion in said slot, said reticule comprising a ring having an annular groove in one face thereof, and reticule retaining means adjustably supported in said hood comprising an annular projection adapted to enter the groove in said reticule when said reticule is in operative position within said slot, thereby positioning and retaining said reticule in said hood.

3. In a firearms sight, in combination, a cylindrical hood having therein a semi-cylindrical transverse slot adapted to receive and support a reticule, a reticule adapted for insertion in said slot, means for retaining said reticule in operating position within said slot comprising a continuous circular groove in one face of said reticule, and a tubular member threaded into said hood and CRAWFORD C.
