Minute of Angle (MOA) and Milliradian (MRAD, also known as mil) are two units of angular measurement used in long-range shooting to adjust sights and estimate distances. At 100 yards, one MOA subtends approximately 1.047 inches, while one MRAD subtends approximately 3.6 inches. This difference in subtension at a given distance forms the core of the MOA vs. MRAD debate.
Precise aiming and accurate adjustments are crucial for successful long-range shooting. Choosing the right angular unit influences how shooters adjust their optics, interpret range estimations, and communicate with other shooters. Understanding the strengths and weaknesses of each system allows for informed decisions based on individual preferences, equipment capabilities, and specific shooting disciplines. Historically, MOA has been the more traditional unit, especially in American shooting sports. However, the metric nature and arguably more intuitive calculations associated with MRAD have led to its increasing popularity.
