Olight Osight SE

• Fully Enclosed Emitter: The sealed design keeps dirt, water, sweat and lint away from the emitter, so the dot stays visible and reliable during everyday concealed carry and in poor weather.
• 2 MOA Dot & 32 MOA Circle: The multi-reticle system switches between dot only, circle only or dot and circle, letting the shooter choose a precise aiming point or a fast reference for close-range shooting.
• Side-Loading CR1620 Battery: The battery can be replaced without removing the sight from the slide, so the zero is preserved. Runtime reaches up to 75,000 hours, and a low-power indicator warns when replacement is due.
• Motion Sensor: The sight switches on with movement and turns off after 3 minutes of inactivity, keeping it ready for use while conserving battery life.

ABOUT THE OSIGHT SE SERIES

The Olight Osight SE series is a range of compact, enclosed emitter red dot sights designed primarily for concealed carry, self-defence and training with optics-ready pistols. The series belongs to Olight's Osight family of reflex sights and focuses on a small, low-profile housing that suits subcompact and slim carry handguns.

The fully sealed design protects the emitter from rain, dust, debris and moisture – conditions that can obscure the dot on open-emitter sights. Inside, an aspherical lens provides a distortion-free and parallax-free sight picture, while the low deck height allows co-witnessing with most factory iron sights.

Osight SE sights are offered in several mounting versions, including the RMSc footprint, a direct-mount version for Glock MOS slides and a DPP footprint version. Reticle options include the 2 MOA dot with 32 MOA circle multi-reticle system as well as a single 6 MOA dot, with both red and green illumination available depending on the variant.

Common features across the series include a side-loading CR1620 battery, a motion sensor with automatic shut-off, daylight and night vision-compatible brightness settings, and an IPX7 waterproof rating.

ABOUT THE MODEL (OLIGHT OSIGHT SE)

The Olight Osight SE is a compact enclosed red dot sight with the RMSc footprint, intended for carry pistols with optics-ready slides. With a weight of just 27.5 g and dimensions of 40.4 × 24.9 × 24.6 mm, it adds very little bulk to the pistol, which makes it practical for concealed carry, home defence and range training.

The red multi-reticle system offers three modes. The 2 MOA dot is suited to precise shots at longer pistol distances, the 32 MOA circle supports fast target acquisition at close range, and the combined dot-and-circle mode provides a balance of both. The reticle uses a 650 nm red LED, and the 21 × 14 mm window with multi-coated optics and an aspherical lens provides a clear, parallax-free view with unlimited eye relief, so the shooter can keep both eyes open and focus on the target.

Brightness can be set across 10 levels – 8 daylight and 2 night vision-compatible settings – covering conditions from bright sunlight to complete darkness. The motion sensor turns the sight on as soon as the pistol is moved and switches it off after 3 minutes without movement. Together with the CR1620 battery, this gives a runtime of up to 75,000 hours (level 3, dot only). The side-loading battery tray allows battery replacement without removing the optic from the slide.

Windage and elevation adjust in 1 MOA clicks with a travel range of ±35 MOA. Thanks to its low deck height, the sight allows co-witnessing with most factory iron sights, so suppressor-height sights are not required for a backup sight picture.

The housing is CNC-machined from 7075 aluminium, rated IPX7 waterproof and drop-resistant from 1 m, making it suitable for the demands of daily carry and use in rain or dusty conditions.
