ABSTRACT:
The invention comprises a reticle assembly for an optical sight. In accordance with one embodiment of the invention, a reticle assembly (58) may comprise a housing (302) having a first slot (322) formed along an inside surface (304) by a first set of opposing side walls (318). A cross slide (330) may disposed in the first slot (322). The cross slide (330) may include opposing edges (334) engaging the first set of opposing side walls (318). The cross slide (330) may include a second slot (340) formed by a second set of opposing side walls (346) substantially normal to the first set of opposing side walls (318). A reticle holder (350) may be disposed in the second slot (340). The reticle holder (350) may include opposing edges (358) engaging the second set of opposing side walls (346). The reticle holder (350) may include a viewing aperture (354). A reticle (300) may be coupled to the reticle holder (350) in alignment with the viewing aperture (354). The viewing aperture (354) may overlap an elongated aperture (332) of the cross slide (330), which may overlap an extended aperture (308) of the housing (302).
