mrad - milliradians, estimating distance using the rifle scope
Estimating the distance to the target using a rifle scope with a MilDot reticle and adjustment turrets with MRAD (Milliradian) subdivisions. The angle measure MRAD (also called Mil) describes the adjustment of sight in relation to the barrel of a firearm. If the riflescope has the reticle in the 1st image plane, it increases in size when zooming. Only when the reticle is magnified is it in the correct ratio to the respective magnification factor and allows correct calculation of the distance or size of an object.
