OLIGHT OSIGHT C Red Dot Sight — Black

The OSIGHT C is an enclosed red dot sight with an RMR footprint, designed for pistols and compact carbines where weight and size matter. With a CNC-machined 7075 aerospace aluminium body and a weight of 42 g, it mounts directly onto any slide or rail cut to the RMR standard without adapters.

The reticle offers three selectable modes: a 3 MOA dot for precise aiming at distance, a 32 MOA circle for rapid target acquisition at close range, and a combination of both for those who want two references in a single setting. The trade-off is real: the circle occupies a significant portion of the 24×19 mm window — ideal on target at a few metres, but less convenient when engaging a narrow target beyond thirty. Shooters who work primarily at close range will find a clear advantage in the circle; those who alternate between distances will prefer the combined mode or the dot alone.

The 10 brightness levels — 8 daylight and 2 night-vision compatible — cover the full operational range from bright sunlight to low-light environments. The motion sensor activates the sight automatically and switches it off after 3 minutes of stillness, extending battery life to up to 100,000 hours in single-dot mode at level 3. The last-used brightness setting is stored in memory, so there is no need to reconfigure the unit each time it is switched on. Windage and elevation adjustment covers ±45 MOA with 1 MOA clicks, providing enough travel to correct any imperfectly centred mount. IPX6 waterproofing ensures reliable operation in heavy rain without special precautions.

Key features

• The RMR footprint allows direct mounting on pre-cut slides and a wide range of aftermarket mounts, with no adapter plates required.
• Three selectable reticles — dot, circle, and combination — let you match the aiming reference to your operational distance without changing optics.
• The motion sensor with 3-minute auto-off extends CR1632 battery life to up to 100,000 hours, eliminating the risk of a dead sight when you need it.
• NV compatibility across 2 dedicated levels makes the OSIGHT C usable with night-vision devices without washing out the reticle.
• The 7075 CNC aluminium body weighs just 42 g: minimal bulk on the slide without affecting the balance of the pistol.
