What Does MOA (Minute of Angle) Mean on a Gun?
When it comes to shooting and firearms, there are a lot of technical terms that can seem overwhelming, especially for newcomers to the world of marksmanship. One of those terms is MOA, or Minute of Angle. But what does MOA mean on a gun, and how does it affect the way you shoot?

Definition of MOA
Before we dive into what MOA means on a gun, it’s important to understand its definition. A minute of angle, or MOA, is a unit of measurement used to express the subtlety of a precision rifle scope. In short, MOA refers to the ability of a rifle scope to provide a minute of accurate range, making it an important consideration when choosing the right scope for your firearms needs.
In simpler terms, MOA is the smallest amount of movement, measured in radians, that can be easily detected and targeted by an average shooter. This amount of movement is equivalent to about 1/10th the thickness of a human hair. If you’ve ever tried using a low-quality scope before, you’ll know why this can make a world of difference when it comes to hitting your mark accurately.
Measuring Accuracy: MOA vs. DPI (Dots Per Inch)
You may have seen scopes measured in dots per inch (DPI), but what exactly does that mean? When a scope has a higher DPI rating, it means it can provide more subtle adjustments when making aim corrections. Conversely, MOA-rated scopes focus on delivering consistent, accurate movements based on the average shooter’s skill level. Here’s a comparison in a nutshell:
| Metric | Meaning | Example Scope |
|---|---|---|
| 1/4 MOA | Minute of Angle precision | Aimpoint 3.5-11.5×50 MM, 65074 (Scope) |
| 0.2 DPI | Dots per Inch accuracy | Leupold 4.5-14×40 QRW Riflescope |
| Scope | Features | Price Range |
|---|---|---|
| Aimpoint 3.5-11.5×50 MM, 65074 (Scope) | Excellent low light visibility, built-in mounting plate | $ 750-$ 1500 |
| Leupold 4.5-14×40 QRW Riflescope | Waterproof design, lightweight | $ 1,200-$ 2000 |
Why Should You Care About MOA?
Here are just a few key reasons why you should concern yourself with the MOA rating on a gun:
• Increased Accuracy: A high MOA scope allows you to make subtler aim adjustments, increasing the accuracy of your shots.
• Enhanced Customization: With the right MOA scope, you can better fine-tune your rifles to compensate for parallax and scope movement, ensuring even greater accuracy over long ranges.
• Better Versatility: A scopes with multiple reticle systems and interchangeable MOA and DPR configurations mean you can use the scope for multiple tasks, be it precision long-range engagements or even self-defense, without worrying about limitations imposed by other features.
As you weigh your options among different rifles and scopes, remember: understanding the language of marksmanship, in this case MOA, will allow you to make a more informed buying decision for your firearms arsenal.
In summary, to answer the initial question what does MOA (Minute of Angle) Mean on a Gun?: MOA represents the capability of a scope to help you land accurate shots within a minute-of-angle diameter. Choose the right MOA for your riflescopes when you value accuracy, customized adjustments, and versatility at the firing range. Always remember the phrase: understanding MOA matters!
