When it comes to building or customizing an AR-15, one of the most critical decisions you’ll make is choosing the right minute of angle (MOA) for your rifle scope. With so many options available, it can be overwhelming to determine which MOA is best for your specific needs. In this comprehensive guide, we’ll delve into the world of MOA, explore the different types, and provide you with the knowledge to make an informed decision.
Understanding MOA: The Basics
Before we dive into the best MOA for your AR-15, it’s essential to understand what MOA is and how it works. MOA is a unit of measurement used to express the size of a rifle scope’s adjustment increments. In simpler terms, it’s a way to measure how much the bullet will move when you adjust the scope’s windage or elevation.
One MOA is equivalent to 1.047 inches at 100 yards, making it a relatively small unit of measurement. To put it into perspective, at 100 yards, a 1 MOA adjustment would move the bullet about the width of a human hair. As the distance increases, so does the size of the MOA. For example, at 500 yards, 1 MOA would be approximately 5.23 inches.
Types of MOA: Which One is Right for You?
There are several types of MOA available, each catering to different shooting styles, distances, and preferences. Here are some of the most common:

What is MOA and why is it important in AR-15 rifles?
MOA, or Minutes of Angle, is a unit of measurement used to express the accuracy of a rifle or a scope. It’s defined as one-sixtieth of a degree, and it’s used to measure the angular distance between the rifle’s bore and the bullet’s impact point. In simpler terms, MOA is a way to describe how accurate a rifle or scope is, with a smaller MOA indicating a higher level of accuracy.
In an AR-15 rifle, MOA is critical because it determines the rifle’s ability to hit its target consistently. A good MOA ensures that the bullet will land close to the aim point, even at longer ranges. This is especially important for competitive shooters, hunters, and law enforcement personnel who require high accuracy in their shooting. Choosing the right MOA for your AR-15 can make a significant difference in your shooting performance and overall confidence in your rifle.
What are the different types of MOA available for AR-15 rifles?
