Red dot sight OLIGHT Osight SE MOS

Olight Osight SE MOS is an enclosed red dot sight manufactured by Olight, a brand known for its high-quality flashlights, headlamps, and weapon lights. It is designed specifically for compatible full-size GLOCK® MOS pistols. The sight features a direct MOS mount, eliminating the need for a separate adapter plate on compatible firearms. The large 23 x 18 mm sight window makes the dot easier to acquire and speeds up sight picture acquisition.

Olight Osight SE MOS is a battery-powered red dot sight designed specifically for compatible GLOCK MOS pistols. Its direct MOS mount allows installation without a separate adapter plate, resulting in a simple and low-profile setup. Compared with traditional iron sights, the Osight SE MOS enables faster aiming while allowing both eyes to remain open and focused on the target.

The red reticle of the Osight SE MOS consists of a 2 MOA dot and a 32 MOA circle, which can be used either together or separately. The crisp reticle and large 23 x 18 mm sight window make the dot easier to acquire during fast presentations and while the firearm is moving. The aspherical lens is designed to minimize optical distortion and provide a clear, parallax-free sight picture. The enclosed design protects the emitter from rain, snow, dust, and dirt.

Offering a runtime of up to 140,000 hours, the sight is powered by a single CR1632 battery. The battery compartment opens from the side of the sight, allowing the battery to be replaced without removing the optic from the firearm or disturbing the zero. The motion sensor automatically powers the sight down after approximately 3 minutes of inactivity and instantly reactivates the reticle when movement is detected. The memory function restores the previously used brightness setting. There are 10 brightness levels in total, with eight intended for daylight use and two for use with night vision devices. The housing is made from durable 7075-T6 aluminum alloy, and the sight has an IPX7 waterproof rating.

Quick guide

• On/Off: Turn the sight on by pressing either button (+ or -). Turn the sight off by pressing and holding the + and - buttons simultaneously.
• Reticle selection: Choose between the 2 MOA dot + 32 MOA circle, 2 MOA dot only, or 32 MOA circle only.
• Brightness adjustment: Brightness is adjusted using the + and - buttons. Eight daylight brightness levels and two night vision-compatible levels are available. The sight remembers the last used brightness setting and restores it when powered on.
• Motion sensor: When the motion sensor is enabled, the sight automatically enters sleep mode after remaining stationary for approximately 3 minutes and immediately powers back on when movement is detected.
• Battery replacement: The CR1632 battery is replaced through the battery compartment on the side of the housing, so the sight does not need to be removed from the firearm during battery replacement.
