Sightmark riflescopes Mil-Dot reticle Mil stands for millradian. A millradian is 1/6283.2th of a circle, or 3.438 MOA. The millradian represents 1 unit at 1000 yards. To simplify, a target that is one yard tall at 1000 yards would measure 1 millradian.
Sightmark’s Mil-Dot reticle is the NATO standard MilDot, which differs from the ¾ USMC reticle. In order to accurately range using the Mil-Dot system, the target size must be known. For example, a full size deer is approximately six feet long. Transfer the feet into yards (3’ = 1yd), so the deer is 2 yards long. Now measure the deer in the crosshairs; it is 4 mils long. Then divide the size of the deer by the Mils. 2/4=0.5 then multiply 0.5 by the constant of 1000. This equals 500. So the deer is roughly 500 yards away. Finally, adjust the riflescope’s elevation for accuracy.
