MOA vs MIL: How to Read Your Scope

Both MOA and MIL are just angles — ways to measure how far your bullet lands from your aim, in a unit that grows with distance. Here's what they mean and how to use them.

MOA — Minute of Angle

One MOA is about 1.047 inches at 100 yards — so, near enough, "an inch per hundred yards." At 200 yards one MOA covers ~2 inches, at 300 ~3 inches, and so on. Most MOA turrets click in ¼ MOA, so one click moves impact ¼ inch at 100 yards, ½ inch at 200.

MIL — Milliradian

One MIL is 3.6 inches at 100 yards (3.438 MOA). It's a metric-friendly angle: 1 mil is 10 cm at 100 m. Most MIL turrets click in 0.1 MIL, worth 0.36 inch at 100 yards. MIL is the common choice for precision and long-range shooting because the reticle and turrets pair cleanly.

Subtension: it grows with distance

The single most useful fact: one unit of angle covers more inches the farther out you go. One mil is 3.6″ at 100 yards, 7.2″ at 200, and 18″ at 500. That's why the same "2 inches low" needs fewer clicks at 300 yards than at 100 — the app handles the conversion for you.

Which way do I turn?

Turrets are marked U/D (up/down) and L/R (left/right) for where the impact moves. Group low and left? Dial UP and RIGHT. Enter your miss on the Dial-In tab and AHL Sight gives you the exact clicks and direction — no mental math.

Match reticle to turrets

Use a MIL reticle with MIL turrets, or MOA with MOA. When they match, a hold you read in the reticle is the same number you'd dial — no converting under pressure. Mixing them (a MIL reticle with MOA turrets) is a classic source of misses.

AHL Sight is a planning aid. Always confirm your zero with live fire and follow all firearm safety rules.
