Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right).
To adjust a 1 ⁄ 4 MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 4 = 12 clicks down and 1.5 × 4 = 6 clicks right; To adjust a 1 ⁄ 8 MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 8 = 24 clicks down and 1.5 × 8 = 12 clicks right; Comparison of minute of arc (MOA) and milliradian (mrad).
Diagram illustrating the relationship between distance, group size on the target (subtension) and angular group size Mean point of impact (MPI) is the calculated center of the grouping, which is the average center of all the shots, and is not necessarily located at a hole in the target. [ 2 ]

The rear sight features a windage drum that can be adjusted during zeroing with about 1 MOA increments. The front sight is a tapered round post of approximately 0.0625 in (1.59 mm) diameter adjustable during zeroing in about 1 MOA increments. A cartridge or tool is required to (re)zero the sight line.

The M24 originally came tapped for the Leupold Ultra M3A 10×42mm fixed-power scope, which came with a circle-shaped mil-dot glass-etched reticle. This was later replaced in 1998 by the Leupold Mk 4 LR/T M1 10×40mm fixed-power scope with an elongated-shaped mil-dot wire reticle. [ 5 ]
