5.56 NATO / .223 Rem Drop Chart

The AR-15 standard — fast and flat up close. The light 55 gr load sheds velocity and drops off past 400 yards; heavier 77 gr stays in the fight much farther.

Stays supersonic to roughly 600 yards — past that the bullet goes transonic and groups usually open up.

Estimate — confirm at the range. These figures are computed for the selected load and zero at sea level. Your real drop depends on your exact ammo, barrel length, zero, altitude, temperature, and conditions. Use this to get in the ballpark and to pick the right optic — then verify your actual come-ups on paper or steel before you trust them.

What this means for your optic

By the time you're holding several MOA or MIL of holdover, a plain dot stops being enough. That's where a reticle with marked holds (a BDC or MIL/MOA grid), an exposed turret you can dial, and a first-focal-plane scope earn their keep. Pick a rifle below to see the optics that fit it — and how they mount.
