Rifle Zero — 50 Yards
A 50-yard zero is favored by many modern carbine instructors as the best all-around single zero for a red-dot AR-pattern rifle. It trades away the 25-yard zero's coincidental re-alignment at 300 yards in exchange for a flatter, more forgiving trajectory across realistic engagement distances out to roughly 200 yards, with less exaggerated mid-range rise.
Before you start
Zero from a stable, supported position (a rest, bags, or a barricade) — zeroing measures the relationship between your sight and your bore, not your own unsupported wobble. Confirm every zero with a second group after adjusting, and re-torque and recheck your mount once you're done. Click values (MOA or MRAD per click) vary by optic model — check your specific optic's manual before converting inches to clicks.
Step-by-Step Zeroing Procedure
- Mount and torque the optic or confirm iron sights are tight. Check eye relief and cheek weld for consistency.
- Shoot from a supported position at 50 yards. Fire a 3-5 shot group at one consistent point of aim.
- Measure the group's offset from your point of aim, in inches and direction.
- Convert to clicks and adjust. At 50 yards, 1 MOA is about 0.52 inches. For a 1/2-MOA-per-click optic, that's roughly 0.26 inches per click; adjust in the marked direction.
- Re-shoot and confirm with a second, then a third independent group at the same point of aim.
- Know the tradeoff. Unlike the 25-yard BZO, this zero won't coincidentally realign at 300 yards — past about 200-250 yards you'll need to hold over as the bullet drops below point of aim.
Frequently Asked Questions
- Is a 50-yard zero better than a 25-yard zero?
- Neither is universally "better" — they're different tradeoffs. A 50-yard zero gives a flatter, more forgiving trajectory out to roughly 200 yards with less mid-range rise, which many instructors prefer for typical carbine distances. A 25-yard zero also re-aligns near 300 yards, which some prefer for a single zero covering close-to-long range.
- How much does a 50-yard zero drop at 300 yards?
- Enough that you'll need a real holdover — this zero is not optimized to re-align at long range the way a 25-yard BZO coincidentally does. Expect several inches to a foot or more of drop by 300 yards depending on your load and barrel length.
- What MOA-per-click conversion do I use at 50 yards?
- 1 MOA is about 0.52 inches at 50 yards. For a 1/2-MOA-per-click optic, that's roughly 0.26 inches per click — divide your measured offset in inches by that figure to get the number of clicks.
