Reticle Details

The Target Dot .125 reticle is used for Target shooting in high power and ED glass target scopes. It features a fine crosshair with a fine 1/8 MOA dot in the center. The slightly larger dot is necessary due to the larger field of view. This reticle is ideal for short range .22 rimfire, mid-range center fire.
