3 moa vs 6 moa – Know The Difference

No shooter wants to miss shots on the field, especially in a combat situation. You can not get your accurate shot by choosing the right gun with the right optic. It would be best to learn what Moa is and how it works to get your shot right. Selecting the right Moa can be confusing for shooters, but it is too important a topic to ignore. 

The range of Moa available in the market is from 1 to 12 Moa. But here, we will discuss the difference between a 6 Moa and 3 Moa. This 6 moa vs. 3 moa comparison will help you choose the Moa of your preference.

What is Moa?

Moa is the angular measurement that is equal to 1/60th of a degree. For understanding it better, consider a circle. We know that a circle has 360 degrees. Out of that 360 degrees, take 1 degree out. Further, divide that 1 degree into 60 parts. Now you have the 60th part of 360. This tiny part makes a big difference in the accuracy of your shot.

3 Moa vs 6 Moa: The Difference

The main difference between a 3 moa and a 6 moa is that the 3 moa is a smaller dot, while the 6 moa is a bigger dot. The smaller size of the 3 moa gives more precision. But at a close range, you need more focus to adjust the 3 moa reticle on the target. It is more suitable to use for long-range shooting. And, the larger 6 moa is brighter and more visible. Due to its visibility, it is easier to track. So, a 6 moa dot gives faster target acquisition.

Moa and Red Dot Sights

Moa comes into play while we use a red dot sight. Red dot sights have become popular due to their quicker target acquisition. You don’t need to align your weapon’s front and rear sight with the target in a red dot sight. You place the reticle or red dot on the target you want to hit. It would help if you had Moa for achieving accuracy in hitting your target. 

3 Moa

Are you wondering what 3 moa is? 1 moa equals 1-inch at 100 yards. So, 3 moa is 3 inches at 100 yards. In other words, at 100 yards, a reticle with 3 Moa will cover a 3-inch diameter or make a 3-inch circle. At 50 yards, it will cover a 1.5-inch diameter, and at 25 yards, the diameter will reduce to 0.75 inches. 

You can also say that a 3 moa will produce tight small groups.

6 Moa

Like 3 Moa, a 6 moa is equal to 6-inches at 100 yards. At 50 yards, it becomes 3-inches, and at 25 yards, it further reduces to 1.5-inches. We have already mentioned that a 3 moa reticle will make a 3-inch circle on the target. Following the same principle, a 6 moa reticle will cover a 6-inch diameter or make a 6-inch circle.
