Understanding MOA

MOA (Minute of Angle) is the go-to measurement for your weapon's accuracy. Think of it like this: you might brag about your car being fast, but there’s a big difference between saying "this car is fast" and "this baby hits 0 to 60 mph in 3 seconds." The same goes for your firearm. Instead of just calling it “accurate,” you can confidently say, "this rifle shoots sub-MOA at a hundred yards easy." Whether you’re adjusting your scope, compensating for wind, or trying to hit a distant target, knowing your MOA gives you the control you need to shoot with confidence. 

What Is MOA Anyway?

Let’s keep it simple: Minute of Angle is a unit of measurement used to describe angles. In the shooting world, it’s how we measure adjustments on your optic or scope to align your point of aim (what you’re looking at) with your point of impact (where your bullet hits).

Remember: 1 MOA equals 1 inch at 100 yards. So, if your shot lands 1 inch off the target at 100 yards, you’ll need to adjust by 1 MOA to get back on track. Easy enough, right?

This chart illustrates how Minute of Angle (MOA) adjustments change with distance. While the common rule of thumb is 1 MOA ≈ 1 inch at 100 yards, the precise measurement is actually 1.047 inches at 100 yards, increasing incrementally with range. As distance increases, the impact of each MOA adjustment grows, meaning a 1 MOA correction at 1000 yards moves the point of impact by 10.47 inches. Understanding these precise values can help you make accurate scope adjustments for long-range precision.

Why Does MOA Matter?

If you’ve ever wondered why your shots aren’t landing where you want them, MOA is the answer. Most modern optics allow you to adjust for windage (left and right) and elevation (up and down) using MOA. The better you understand it, the better you’ll shoot.

MOA Adjustments and Grouping

When we talk about a rifle’s accuracy, we often mention its grouping. A "group" refers to the pattern your shots make on a target. For example, some precision rifles are capable of "sub-MOA groups," meaning their shots land within less than 1 inch of each other at 100 yards—surgical accuracy. Other firearms such as those with shorter barrels might have a group that varies between 3 MOA or larger. It’s important to note that accuracy doesn't depend on just the firearm. Most of the time, the shooter’s skill and consistency can make or break the accuracy of a rifle. The most accurate rifle in the world in the hands of a person who's never picked up a gun before might still be a mile off target. Mastering your windage and elevation adjustments as well as your understanding of MOA is how you take control of your precision.

Most scopes and sights adjust in fractions of MOA, like 1/4 MOA per click. What does that mean? For every click of your optic’s turret:

• At 100 yards, 1 click moves your point of impact 1/4 inch.

• At 200 yards, 1 click equals 1/2 inch.

• At 300 yards, 1 click equals 3/4 inch.

So the farther the target, the more ground each click covers.

How Do You Use MOA?

Let’s say you’re at the range with a target 100 yards out, and your shot lands 2 inches low and 1 inch to the left. Fire a couple of more shots without changing your point of aim, then measure how far that group is from your intended target. Here’s what you’ll do:

1. Adjust up by 8 clicks (2 inches at 100 yards = 8 clicks if your scope adjusts 1/4 MOA per click).

2. Adjust right by 4 clicks (1 inch at 100 yards = 4 clicks).

Here’s an important tip: don’t chase your group. Instead of adjusting your optic after every shot, fire three to five shots first. This gives you a consistent group to work with and helps you avoid over-correcting for a single stray round. Once you’ve established your group, you can make informed adjustments to your scope. This method saves time, ammo, and frustration.

Firefield Sights and MOA

At Firefield, we keep it real simple. Most of our red dot sights and scopes feature easy-to-use MOA adjustments, perfect for beginners who want to build confidence without the hassle. It’s also important to have a riflescope with a wide MOA range to handle different shooting scenarios. Take the Agility II, for example. It features precise 1/4 MOA clicks and offers a total of 60 MOA of windage and elevation adjustments. This means you can make fine-tuned corrections while still having plenty of range to adjust for those longer shots or tricky conditions. Whether you’re zeroing in a red dot for a quick 50-yard shot or dialing in a scope for long-range precision, Firefield has you covered.

The Bottom Line

Understanding MOA is one of the easiest ways to level up your shooting game. With a little practice and the right Firefield optic, you’ll be stacking bullseyes in no time. So, grab your gear, hit the range, and start dialing in that sweet, sweet accuracy.

Stay sharp, stay focused, and as always—keep sending it!
