We’ve handled a lot of micro reflex sights over the years, but the OLIGHT Osight 3 MOA promptly stood out the moment we clicked its charging cover into place. An industry-first twist, that cover doesn’t just protect the optic-it shows an actual percentage readout for both the cover and the optic, and doubles as a power bank. Between the USB-C cover and magnetic charging on the sight itself, we were checking battery levels at a glance instead of guessing.it’s a small quality-of-life upgrade that set the tone for our time with the Osight.
For this review, we mounted the osight on an RMR-cut slide and on a Picatinny rail to see how it behaved on different platforms. Over several range sessions-sunlit outdoor steel,an indoor lane,and a drizzly morning-we paid close attention to its 0.94 x 0.85 in window, the 3 MOA dot (we tested both red and green), and the motion-wake plus auto-off pairing. We also kept an eye on OLIGHT’s battery-life claims (over 70,000 hours on low, more than 17 days on max, and extended runtime via the charging cover) to see how that translated to real use over multiple days of carry and training.
in the sections ahead, we’ll walk through setup and zeroing, brightness and glass quality, battery performance and charging convenience, durability and zero retention, and how the Osight’s modes (manual, lockout, and auto-sensing) affect day-to-day use. By the end, we’ll tell you were the OLIGHT Osight 3 MOA Rechargeable Dot Open Reflex Sight impresses, where it doesn’t, and whether the green or red option makes more sense for your needs.
Our first Impressions After Range Time With This Open Reflex Sight
Right out of the box and onto the bench, we found the sight quick to trust. The 0.94 x 0.85 in window frames targets cleanly, and the 3 MOA dot stayed crisp through recoil, making transitions feel natural. Brightness was easy to dial-between 10 daytime and 2 night levels-while the auto-sensing, manual, and lockout modes gave us control without fuss.Adjusting windage/elevation to a 25-yard default zero was straightforward, and our zero held solid through strings of fire. We also appreciated the motion sensor’s instant wake and the 10‑minute auto-off, which felt smart on the line and in the bag.
- Large window aids fast, consistent acquisition.
- 3 MOA dot balances speed and precision well.
- Auto/Manual/Lockout modes cover duty and training needs.
- Motion wake is responsive; auto-off saves power.
- Zero confidence: manufacturer-tested to 10,000 rounds.
| Window & Dot | 0.94 x 0.85 in, 3 MOA – quick visual lock |
| Brightness | 12 settings (10 day, 2 night) - easy to find “just right” |
| Power & Charging | USB‑C cover + magnetic optic – cover recharges optic up to 3x |
| Battery Endurance | Up to 70,000 hrs (low); 17+ days (bright); ~70 days with cover support |
| Status at a Glance | Cover percentage display + optic tri‑colour indicator |
| Footprint & Mounting | RMR footprint; Picatinny compatible |
| Durability | IPX6 optic / IPX4 cover – range‑ready confidence |
Power management is where this setup feels different in the best way. The charging cover’s percentage readout for both cover and optic takes the guesswork out, while the optic’s tri‑color indicator confirms status on the fly. The cover is USB‑C rechargeable, the optic magnetically docks, and a full cover charge can juice the optic up to three times. Endurance claims are strong-over 70,000 hours on low, 17+ days at max brightness, and extended to 70+ days with the cover-making this a compelling training and competition partner. Add the Ruggedized miniature Reflex footprint for easy integration, green or red dot options, and the steady, almost parallax‑free feel at typical handgun distances, and our first range session left us confident in its role across drills, quals, and match stages.

Performance In The Field Parallax Free Clarity And Green Or Red Dot Choices
In live-fire sessions, we appreciated the parallax-free experience and the clear 0.94 x 0.85 in window that kept the 3 MOA dot crisp during recoil and awkward angles. Dot acquisition was immediate whether we selected the green or red option-green popped in bright sun,while red stayed familiar in mixed light. The optic’s 12 brightness settings (10 daylight, 2 night) and auto-sensing, manual, and lockout modes made it easy to dial in, and the motion sensor woke the reticle the moment we presented the pistol. Zeroing was straightforward at 25 yards,with easy windage/elevation tweaks,and it impressively held POA/POI through a 10,000-round endurance test. Mounting was painless thanks to an industry-standard footprint, and weather resistance (IPX6 optic / IPX4 cover) gave us confidence in rain and range dust alike.
- Parallax-free aiming for consistent point of aim across shooting positions
- Green/Red dot choices to match ambient light and personal preference
- 12 brightness levels including 2 for night-adapted use
- Instant wake and auto-off after 10 minutes for smart readiness
- Rock-solid zero maintained through extended round counts
the power system is where this optic separates itself. The magnetic-charging optic and USB-C charging cover work as a team: the cover’s percentage display shows battery levels for both devices at a glance, while the optic’s tri‑color indicator confirms status on the fly. On its own, the reticle can run 70,000+ hours on the lowest setting or 17+ days at max; add the high-capacity cover and we stretched uptime past 70 days, with the cover delivering up to three top-offs. That meant more reps and fewer battery worries, and the protective cover also kept the lens clean between sessions.
| Mode | Runtime | Field Note |
|---|---|---|
| Lowest | 70,000+ hrs | Set-and-forget endurance |
| Brightest | 17+ days | High noon, no washout |
| With Cover | 70+ days | Three recharges on deck |
