Abstract: A rifle scope indicia system preferably includes a mounting base, a marker turret and a plurality of marker pins. The mounting base is attached to a top of an elevation turret of a rifle scope. The marker turret includes a plurality of marker openings formed at a perimeter thereof for receiving the plurality of marker pins. The marker turret is preferably removably attachable to the mounting base. The plurality of marker pins may be illuminated with an illumination circuit. A light emitting device of the illumination circuit is retained in an internal cavity of the marker turret. An illumination conduction ring is placed below the marker turret to illuminate any translucent marker pins. A reference marker pin inserted into the marker turret may be coordinated with a marker applied to the parallax wheel or the parallax bell of a rifle scope.
