OLIGHT Osight 3 MOA Rechargeable Dot Open Reflex Sight - Long Battery

In this review the OLIGHT Osight 3 MOA open reflex sight is evaluated for shooters who want a compact, rechargeable red or green dot with an innovative charging solution. The standout reason to consider this optic is its industry first magnetic charging cover with a percentage battery display, which not only protects the sight but also lets users monitor and recharge the optic on the go. For anyone prioritizing long runtime, a clear small 3 MOA dot and a large window for quick target acquisition, the Osight delivers a modern package with some practical tradeoffs.

Key Features

• Magnetic charging cover: The included cover displays percentage battery for both the cover and the optic so users can check charge status at a glance and keep the unit protected when stored.
• Exceptional battery life: The optic can run over 70,000 hours on its lowest setting and more than 17 days at maximum brightness, and the fully charged cover can extend runtime by charging the optic up to three times.
• Large viewing window: With a 0.94 in x 0.85 in lens the sight offers a generous sight picture that makes target acquisition easier, even during recoil.
• Clear 3 MOA dot: The sharp 3 MOA reticle is easy to pick up quickly for precise aiming at close to mid ranges.
• Motion sensor and auto-off: The unit wakes immediately with motion and will automatically power off after 10 minutes of inactivity to conserve battery.
• Standard footprint and quick zeroing: The Osight uses the common Ruggedized Miniature Reflex footprint and can be zeroed at typical distances with straightforward windage and elevation adjustments.

Who It's For

The Osight suits hunters, sport shooters, and tactical users who want a rechargeable open reflex sight with long endurance and a compact form that fits most mini reflex cuts. The bright settings and multiple daylight and night brightness levels make it useful for varied lighting conditions.

Shooters who need an extremely rugged, mechanical-only sight or who require an ultra-simple disposable-battery option may look elsewhere; while the Osight is durable and rechargeable, its value is strongest for those who will use and benefit from the magnetic charging cover and the extended runtime it provides.
