Nothing is mentioned about the ranging capability of this scope on here. The hash marks represent what width at 300 400 500 & so on? Yards or meters? — 1 Answer

The reticle is based on a mil-radian design. Mil-radian is a measurement of angle. A single mil is equal to 1cm at 100 meters or
3.6” at 100 yards. Next, the MR reticle is a first focal plane reticle. The advantage of a first focal plane reticle is that
the dimensions of the reticle will be true at any magnification. Therefore, using the reticle for ranging can be done
at any point in the magnification range. The top vertical and left horizontal scales are scaled in 1 mil increments. The bottom and right scales are scaled in .5 mil increments, while after 11 mils the scale is marked in 5 mil increments. Both can be used for range finding and calling shots. Below the horizontal scale, between the 10 mil and 20 mil increments, is a series of horizontal lines that can be used for ranging shoulder width of IPSC or similar silhouette targets. These lines allow for quick
target ranging by matching the shoulder width of the target to the corresponding line. The numbers indicate the
distance in meters, 3 is 300 meters, 4 is 400 meters, etc.
