The Olight Osight C is a compact open-emitter red dot sight built on the industry-standard Ruggedized Miniature Reflex (RMR / 407C / 507C) footprint. It is designed for full-size and compact pistols used for tactical, self-defense, concealed carry and sport shooting.

The reticle is switchable between:

• 3 MOA Dot
• 3 MOA Dot + 32 MOA Circle
• 32 MOA Circle only

This gives you a fine aiming point for precision or a larger circle for fast target acquisition.

A side-loading CR1632 battery lets you replace the cell without removing the optic from the slide, so your zero stays intact. Runtime is up to 75,000 hours on the lowest setting. A motion sensor turns the optic off after 3 minutes of inactivity and wakes it when movement is detected. When battery voltage drops below 2.2V, the reticle triple-flashes once per minute as a low-power warning. Memory function remembers your last brightness setting.

The 24 × 19 mm window uses a multi-coated anti-reflective lens for a bright, clear sight picture. The housing is machined from 7075 aluminum with a hard-anodized finish and is rated IPX7 waterproof. Side buttons control power and brightness and are usable with gloves.
