Abstract: Illuminated optical sight reticle assemblies have a transparent element having opposed major surfaces and a periphery, a reticle image formed on one of the major surfaces of the transparent element, the reticle image defining a selected primary point, and an optical fiber having a first free end positioned proximate the selected primary point and an opposed second end away from the first end and proximate to an illumination source. There may be a fiber support structure having a periphery, and a span element extending from the periphery supporting the fiber. The fiber support structure may be a wire reticle. The fiber support structure periphery may have a first thickness, and the span may have a lesser second thickness. The fiber support structure periphery may be a ring. The span may include a first elongated element extending diametrically across the ring.
