MOA vs MRAD: how to choose your scope's units
Quick answer: MOA and MRAD (mil) are just two different units for measuring the same angles your scope adjusts, like inches versus centimeters. 1 MOA is about 1 inch at 100 yards; 1 mil is 3.6 inches at 100 yards. Neither is more accurate. Choose MOA if you think in inches and yards (common for hunters); choose MRAD if you shoot precision or competition, where decimal math and spotter communication are faster. The only hard rule: your reticle and your turrets must use the same unit.
What MOA means
MOA stands for minute of angle, which is 1/60th of a degree. At 100 yards that angle covers about 1.047 inches, which almost everyone rounds to 1 inch. It scales with distance: roughly 2 inches at 200 yards, 5 inches at 500 yards. Most MOA scopes adjust in 1/4 MOA clicks, so each click moves your point of impact about a quarter inch at 100 yards. MOA appeals to shooters who already picture their targets in inches and their distances in yards, so the math feels natural.
What MRAD (mil) means
MRAD stands for milliradian, one-thousandth of a radian, usually just called a "mil." At 100 yards a mil covers 3.6 inches, and it scales cleanly: 7.2 inches at 200 yards, 18 inches at 500 yards. Most mil scopes adjust in 0.1 mil clicks (about 0.36 inches at 100 yards). Because corrections are read and called out in simple decimals ("come up 1.2 mils"), mil is faster for communicating with a spotter and is the standard in Precision Rifle Series and military use.
The one rule that actually matters: match your reticle to your turrets
Whichever system you pick, your reticle and your adjustment turrets must speak the same language: a mil reticle with mil turrets, or an MOA reticle with MOA turrets. If you spot your miss as "half a mil low" but your turret dials in MOA, you have to convert on the fly, and that is exactly where mistakes happen under time or pressure. Matching units lets you see a correction in the reticle and dial the same number on the turret with no math.
MOA vs MRAD at a glance
| MOA | MRAD (mil) | |
|---|---|---|
| Unit | Minute of angle (1/60 of a degree) | Milliradian (1/1000 of a radian) |
| Size at 100 yds | 1.047 in (rounded to 1 in) | 3.6 in |
| Typical click | 1/4 MOA (~0.26 in at 100 yds) | 0.1 mil (~0.36 in at 100 yds) |
| Thinks in | Inches and yards | Decimals / metric-friendly |
| Common with | Hunters, inch-and-yard shooters | PRS, military, competition |
| Comms example | "Come up 4 MOA" | "Come up 1.2 mils" |
| 1 mil equals | 3.438 MOA | 1 mil |
Which should you choose?
- MOA if you think in inches and yards, mostly hunt, or already own MOA scopes and dope. Finer 1/4 MOA clicks are a small bonus.
- MRAD (mil) if you shoot precision or competition, communicate with a spotter, or want to match the majority of the PRS field.
- Consistency beats the choice. Pick one, use it across your rifles, and match your shooting partners so your dope and calls line up.
Our long-range picks let you pick your language: the Vortex Strike Eagle 5-25x56 comes in EBR-7C MOA or MRAD, and the Diamondback Tactical 6-24x50 uses an MOA reticle. See how they compare in Diamondback Tactical vs Strike Eagle.
FAQ
Is MOA or MRAD more accurate?
Neither is more accurate; they are just different units for the same angles, like inches versus centimeters. MOA turrets usually click in 1/4 MOA (about 0.26 inches at 100 yards) and MRAD turrets in 0.1 mil (about 0.36 inches at 100 yards), so MOA clicks are slightly finer, but the difference is negligible for real shooting. What matters is picking one system and staying consistent.
What does 1 MOA and 1 MRAD equal at 100 yards?
One MOA (minute of angle) is about 1.047 inches at 100 yards, commonly rounded to 1 inch. One MRAD (milliradian, or "mil") is 3.6 inches at 100 yards. Both scale with distance: 1 MOA is about 2 inches at 200 yards, and 1 mil is about 7.2 inches at 200 yards.
Should my reticle and turrets match?
Yes, always. Use a mil reticle with mil turrets, or an MOA reticle with MOA turrets. If you mix them (for example a mil reticle with MOA turrets), your holdovers and dial corrections speak different languages and you will make conversion errors under pressure.
Which should a beginner choose?
If you think in inches and yards and mostly hunt, MOA feels intuitive. If you shoot precision or competition, or want faster decimal-based communication with a spotter, MRAD (mil) is the modern standard most PRS shooters use. Either works; consistency with your reticle and your shooting partners matters more than the choice itself.
What does MOA mean on a rifle scope?
MOA on a rifle scope means minute of angle, the unit its turrets and reticle use to measure adjustments. One MOA is 1/60th of a degree, which covers about 1 inch at 100 yards. A turret marked in 1/4 MOA moves your point of impact about a quarter inch per click at 100 yards, so "come up 4 MOA" means dial 16 clicks to raise impact about 4 inches at that distance.
Is "mil vs moa" the same as MOA vs MRAD?
Yes. "Mil" is just the common name for MRAD (milliradian), so "mil vs MOA" and "MOA vs MRAD" are the same comparison. One mil equals about 3.438 MOA, and both are simply units for the same angles your scope adjusts. Everything on this page applies whether you call it mil or MRAD.
