What does MOA stand for in shooting optics?

MOA stands for "Minute of Angle." This term is essential in shooting and optics because it serves as a unit of angular measurement used to describe the accuracy of a firearm's sighting system. One MOA is approximately equal to 1/60th of a degree, which translates to roughly 1 inch at 100 yards. This means that if a rifle is said to be capable of shooting within 1 MOA, it is likely to group shots within a 1-inch radius at that distance, indicating a high level of accuracy.

Understanding MOA is crucial for shooters as it helps them make the necessary adjustments to their sights and understand how their bullet paths will change over various distances. It directly influences how a shooter zeroes their firearm and compensates for factors like wind and range. Mastery of MOA is vital for precision shooting, ensuring effective and accurate shooting performance at varying distances.
