The Olight Osight Green 3 MOA is a rechargeable red dot sight built on the industry-standard Ruggedized Miniature Reflex footprint. Instead of a coin-cell you replace, this pistol optic uses a magnetic charging cover with its own battery display — giving you a 3 MOA green dot in a large viewing window with runtime measured in tens of thousands of hours.
Key Features
-
Industry-first magnetic charging cover with a battery display showing charge level for both the cover and the optic
-
3 MOA dot in a large window — a 0.94" × 0.85" lens for fast, precise dot acquisition under recoil
-
Exceptional runtime: 70,000+ hours on the lowest setting, 17+ days on the brightest, extended to 70+ days with the charging cover
-
Motion and light sensor: shuts down after 10 minutes of inactivity and wakes instantly; auto-sensing mode picks the best brightness
-
12 brightness levels — 10 daylight and 2 night settings in manual mode, plus a lockout mode
-
Unwavering zero confirmed through a 10,000-round field test
-
Industry-standard footprint — Ruggedized Miniature Reflex (407c/507c) for broad optics-ready slide compatibility

Frequently Asked Questions
What size is the dot on the Olight Osight Green 3 MOA?
The Olight Osight Green 3 MOA uses a 3 MOA green dot in a 0.94" by 0.85" window, which is large enough for fast acquisition while staying precise enough for accurate shot placement.
What footprint does the Olight Osight Green 3 MOA use?
The Olight Osight Green 3 MOA adopts the Ruggedized Miniature Reflex footprint — the same 407c/507c pattern used across most optics-ready pistol slides — so the Olight Osight Green 3 MOA drops onto a wide range of factory optic cuts.
How is the Olight Osight Green 3 MOA powered and charged?
The Olight Osight Green 3 MOA is rechargeable rather than battery-swap. Its magnetic charging cover carries its own reserve and a battery display that shows charge level for both the cover and the optic, and the cover recharges over USB-C.
How long does the battery last on the Olight Osight Green 3 MOA?
Olight rates the Olight Osight Green 3 MOA at over 70,000 hours on the lowest brightness setting and 17+ days on the brightest, extended to 70+ days when used with the magnetic charging cover.
Does the Olight Osight Green 3 MOA shut off automatically?
Yes. The Olight Osight Green 3 MOA uses a motion and light sensor that powers the optic down after 10 minutes of inactivity and wakes it instantly when moved. An auto-sensing mode selects brightness for you, and manual mode offers 10 daylight levels, 2 night levels and a lockout mode.
Will the Olight Osight Green 3 MOA hold zero?
Olight put the Olight Osight Green 3 MOA through a 10,000-round field test and reports that it maintained zero throughout.
Where can I buy the Olight Osight Green 3 MOA?
You can buy the Olight Osight Green 3 MOA from Going Gear, an authorized Olight dealer, so your optic arrives with full factory warranty coverage.
