This video explains Minute of Angle (MOA) as a unit of measurement for firearm accuracy and optic adjustments. It clarifies that 1 MOA equals approximately 1 inch at 100 yards, scaling proportionally with distance. The content highlights how MOA relates to the size of red dot sights and the click values on scope turrets for making precise adjustments.

Quick Summary

Minute of Angle (MOA) is a unit of measurement for firearm accuracy, where 1 MOA equals approximately 1 inch at 100 yards. This measurement scales with distance, meaning 1 MOA covers 2 inches at 200 yards and 3 inches at 300 yards. MOA is crucial for understanding red dot sizes and making precise adjustments with scope turrets.

Frequently Asked Questions

What does MOA stand for in firearms?

MOA stands for Minute of Angle. It's a unit of angular measurement used to quantify firearm accuracy and make precise adjustments to optics like scopes and red dot sights.

How is MOA related to inches at different distances?

1 MOA is approximately equal to 1 inch at 100 yards. This relationship scales linearly: at 200 yards, 1 MOA covers 2 inches, and at 300 yards, it covers 3 inches. This helps in understanding the size of aiming points and adjustment increments.

What is considered 'sub MOA' accuracy?

Sub MOA accuracy means that a firearm is capable of consistently grouping shots within a 1-inch diameter circle at 100 yards. Achieving sub MOA accuracy often requires high-quality ammunition and a well-tuned rifle and optic system.

How do scope turrets use MOA for adjustments?

Rifle scope turrets are typically marked with MOA values, indicating how much the point of impact will shift per click. Common adjustments are 0.1 MOA or 0.25 MOA per click. Knowing this value allows shooters to calculate the number of clicks needed to correct their aim.
