Understanding Scope Measurements: Choosing Between MOA and MIL Scopes
When it comes to precision shooting, whether you're an experienced hunter, competitive shooter, or involved in tactical applications, the choice of scope can significantly affect your accuracy and overall experience. Among the many factors to consider, one of the most critical is deciding between Minute of Angle (MOA) and Milliradian (MIL) scopes. These two measurement systems are used to adjust for bullet drop, wind drift, and other environmental variables. Understanding the differences between MOA and MIL, and when to use one over the other, can help improve your shooting precision and ensure you're using the right equipment for your needs.
In this comprehensive guide, we’ll break down what MOA and MIL mean, the pros and cons of each system, and help you determine which scope is best suited for your shooting style. We'll also highlight a few recommended products to get you started on your search for the perfect scope.
Understanding MOA and MIL: The Basics
Before diving into the advantages and disadvantages of MOA and MIL scopes, it’s important to understand what these terms represent. Both MOA (Minute of Angle) and MIL (Milliradian) are angular measurements that help shooters compensate for bullet drop and wind drift at various distances.
MOA (Minute of Angle)
One MOA is an angular measurement that is approximately 1/60th of a degree. In practical shooting terms, one MOA corresponds to roughly 1 inch at 100 yards (specifically 1.047 inches, but the difference is negligible for most practical purposes). This means that for every 100 yards of distance, the point of impact of your bullet will shift by about one inch for each MOA adjustment you make.
MOA scopes are widely used, particularly in the U.S., and are favored by hunters and some precision shooters because of their simplicity. The measurements are often familiar and easy to grasp, especially for those who use imperial units (inches and yards) on a daily basis.
For example, if you're shooting at 200 yards and your point of impact is two inches high, a two-MOA adjustment will bring your shot down to the bullseye. The ease of these simple calculations makes MOA a popular choice for many American shooters.
Recommended MOA Scope: Vortex Optics Crossfire II 4-12x50 AO
- MOA Adjustment: 1/4 MOA per click
- Objective lens: 50mm
- Magnification: 4-12x
- Great for: Hunting and long-range shooting
The Vortex Crossfire II is an affordable, high-quality option for those looking for an MOA scope. With a generous magnification range and easy-to-use turrets, this scope is an excellent choice for hunters and shooters who need precision at various distances.
MIL (Milliradian)
On the other hand, MIL is a metric-based angular measurement. One MIL is equal to 1/1000th of a radian, which translates to approximately 3.6 inches at 100 yards. Unlike MOA, which is more intuitive for shooters accustomed to using inches and yards, MIL is based on the metric system, making it slightly less straightforward for some. However, MIL scopes are growing in popularity, particularly among long-range shooters and military professionals, thanks to their compatibility with the metric system and the fact that MIL adjustments cover more distance with each click compared to MOA.
For instance, at 100 yards, adjusting one MIL will move the point of impact 3.6 inches. This makes MIL scopes advantageous for shooters who are operating at extended ranges and need larger adjustment increments per click.
Recommended MIL Scope: Nightforce NXS 5.5-22x56
- MIL Adjustment: 0.1 MIL per click
- Objective lens: 56mm
- Magnification: 5.5-22x
- Great for: Long-range tactical shooting
The Nightforce NXS is a top-tier option for precision shooters who prefer MIL adjustments. With large, easy-to-grip turrets and a reputation for rugged durability, this scope is trusted by professionals and long-range enthusiasts alike.
MOA vs. MIL: Key Differences and Considerations
Both MOA and MIL scopes have their strengths, and neither system is inherently better than the other. However, certain factors may make one more suitable for your shooting style or purpose than the other.
Precision and Finer Adjustments
MOA scopes offer finer adjustment increments compared to MIL scopes. One MOA is equivalent to approximately 1 inch at 100 yards, whereas one MIL is about 3.6 inches. This means that MOA adjustments allow for more precise fine-tuning of your point of impact, especially at shorter ranges. If you need to make smaller adjustments, particularly for hunting or competitive shooting at medium distances, an MOA scope may be more advantageous.
On the flip side, MIL scopes make larger adjustments with each click, which can be beneficial in long-range shooting scenarios. If you're a long-range shooter who frequently needs to make rapid and significant adjustments, the MIL system may provide the efficiency you need.
Ease of Use
For many shooters, the choice between MOA and MIL comes down to familiarity and ease of use. MOA is typically easier for those who are accustomed to using imperial measurements (inches, yards) because the math aligns more closely with those units. For instance, one MOA equals approximately one inch at 100 yards, making it intuitive for hunters and shooters who are used to thinking in terms of inches.
MIL, being a metric-based system, is less intuitive for those used to the imperial system, but it has its advantages in terms of consistency, particularly for long-range and tactical shooters who are used to working in meters and centimeters. If you're comfortable with the metric system, MIL might feel more straightforward, especially if you're using other metric-based equipment.
Long-Range Applications
For long-range shooting, both MOA and MIL can be effective, but MIL tends to be the more popular choice among professionals in military and law enforcement due to its simplicity in ballistic calculations over long distances. MIL-based reticles often feature cleaner and more simplified designs, making them ideal for quick ranging and holdovers.
That said, many long-range competitors still prefer MOA for its finer adjustment capabilities, particularly in precision shooting competitions where the smallest adjustments can mean the difference between winning and losing.
Recommended Long-Range Scope: Leupold Mark 5HD 5-25x56 MOA/MIL
- Available in both MOA and MIL versions
- Objective lens: 56mm
- Magnification: 5-25x

Which Scope Is Right for You?
Now that you understand the basic differences between MOA and MIL scopes, the next step is deciding which one is best for your specific needs. Consider the following factors when making your decision:
- Familiarity
- If you’re more comfortable with inches and yards, an MOA scope will likely feel more intuitive.
- If you’re used to the metric system or prefer working in meters, a MIL scope will be easier to understand.
- Precision
- MOA scopes offer finer adjustments, making them ideal for shooters who prioritize small, precise changes in their point of impact.
- MIL scopes cover more ground with each click, making them better suited for long-range shooters who need to make larger adjustments quickly.
- Shooting Application
- Hunting: MOA scopes are typically preferred for hunting due to their finer adjustment capabilities and ease of use at closer ranges.
- Long-Range/Tactical Shooting: MIL scopes are often favored by long-range and tactical shooters due to their larger adjustment increments and cleaner reticle designs.
- Type of Shooting
- If you are involved in competitive shooting or hunting where distances vary, MOA may feel more practical.
- For professional, military, or extreme long-range applications, MIL will likely suit your needs better.
Final Thoughts
Ultimately, the choice between MOA and MIL comes down to personal preference, familiarity, and the type of shooting you engage in most frequently. Both systems are highly effective, and there are excellent scopes available in both MOA and MIL configurations to suit your needs. Whichever system you choose, it's important to invest in a high-quality scope that fits your specific shooting requirements.
