I often hear gun accuracy expressed in terms of âMOA,â but with no explanation of what a MOA is. What is a MOA? â Charles B. A: MOA stands for âMinute Of Angle,â which is a unit of angular measurement. When the accuracy of a gun is given in minutes of angle, it is possible for a person to know approximately what size groups the gun shoots within its effective range. There are 360 degrees in a circle, and 60 minutes of arc in each degree, totaling 21,600 minutes of angle in a complete circle. Imagine the shooter is at the center of a circle, and that the target is on the edge of that circle.
