The main difference between MOA and MIL is the angular measurement system used for scope adjustments and reticle holds. MOA uses minutes of angle, while MIL uses milliradians. Neither system is inherently more accurate—the best choice is usually the one that matches your reticle, turret adjustments and the measurement system you are most comfortable using.
At 100 yards, 1 MOA equals about 1.047 inches, while 1 MIL equals 3.6 inches. Most MOA scopes adjust in ¼-MOA clicks, while many MIL scopes adjust in 0.1-MIL clicks.
This guide explains how MOA and MIL reticles work, how their adjustments compare and what shooters should consider when choosing between them.
What Is an MOA Reticle?
MOA stands for Minute of Angle, a unit of angular measurement.
-
1 MOA = 1.047 inches at 100 yards (often rounded to 1").
-
Most MOA scopes adjust in ¼ MOA clicks — meaning each click moves the point of impact about 0.25 inches at 100 yards.
Advantages of MOA:
-
Easier to visualize in inches, since most shooters in the U.S. think in imperial measurements.
-
Finer adjustment with ¼ MOA clicks.
-
Ideal for hunters and marksmen shooting within 1,000 yards.

What Is a MIL or Mil-Dot Reticle?
Mil-Dot reticles use milliradians (mils) to measure angle.
-
1 Mil = 3.6 inches at 100 yards (or 10 cm at 100 meters).
-
Most Mil scopes adjust in 0.1 Mil clicks, which equals 0.36 inches at 100 yards.
Advantages of Mil-Dot:
-
Easier math when working with metric units.
-
Widely used in military and tactical shooting.
-
Faster for range estimation using the reticle.
MOA vs MIL: Side-by-Side Comparison
| Feature | MOA | Mil-Dot |
|---|---|---|
| Measurement Unit | Minutes of Angle (1 MOA ≈ 1” at 100 yds) | Milliradians (1 Mil ≈ 3.6” at 100 yds) |
| Adjustment Clicks | ¼ MOA (0.25” at 100 yds) | 0.1 Mil (0.36” at 100 yds) |
| Best For | Shooters comfortable with yards/inches and MOA-based holds | Shooters comfortable with MIL-based holds and decimal adjustments |
| Ease of Use | Simple in inches | Simple in meters |
| Precision | Commonly ¼-MOA adjustments | Commonly 0.1-MIL adjustments |
MOA vs MIL Conversion
MOA and MIL measure the same thing—angle—but use different units.
1 MIL ≈ 3.438 MOA
1 MOA ≈ 0.291 MIL
At 100 yards:
1 MOA ≈ 1.047 inches
1 MIL = 3.6 inches
You normally do not need to convert between the two systems while shooting. The easiest setup is usually a scope with matching turrets and reticle—for example, an MOA reticle with MOA adjustments or a MIL reticle with MIL adjustments.
MOA vs MIL: Which Scope Reticle Should You Choose?
-
If you primarily shoot in yards/inches and prefer fine adjustments, MOA may feel more natural.
-
If you train or compete with a military/tactical background, or often work in meters/metric, Mil-Dot will be a better fit.
At the end of the day, both systems are accurate and effective — the real key is to stick with one and master it.
Final Thoughts
Both MOA and Mil-Dot reticles are tried-and-true systems. Neither is “better” — but one may be more practical depending on your background, preferred measuring system, and shooting style. Choose the one that feels most intuitive, and spend your time practicing with it rather than switching back and forth.
