Our brand new 30x WA-R eyepiece was designed for the professional hunter and long range precision shooter. The rangefinding reticule, facilitates precise range estimation in the field and also, quick trajectory correction calls by the spotter, in relation to point of impact achieved. The reticule "GRID" if you will, is designed in Mils and 1/2 Mils increments for maximum precision. It has 15 mils of elevation markings and 20 Mils of windage markings: 10 Mils to the left and 10 Mils to the right. The upper half of the image was purposly left open, to offer a clear and unobstructed field of view.
