Green Circle Dot Reticle Options

The Olight Osight C offers three reticle configurations to match your shooting preference and application. The 3 MOA dot provides a precise aiming point for accuracy focused shooting. The 32 MOA circle creates a fast acquisition reference for close quarters work. The dot and circle combination pairs precision with speed, giving you a fine aiming point inside a larger reference circle. Green reticle color offers high visibility in bright conditions and reduced bloom compared to red in night vision compatible modes.

Side Loading Battery System

The side loading battery design allows CR1632 battery replacement without removing the optic from your pistol. This maintains your zero and eliminates the need to re-zero after battery changes, saving time and ammunition. The flush fit battery tray keeps the housing profile low without protruding edges. The low battery indicator flashes the reticle three times when voltage drops below 2.2V, giving you advance warning before the battery dies completely.

Motion Activation and Auto Shutoff

Motion activation wakes the optic when it detects movement, eliminating the need to manually power on the sight during presentation. Auto power off after three minutes of inactivity conserves battery life during storage or carry. This combination ensures the optic is ready when you need it while maximizing battery longevity between changes. The system works seamlessly in both concealed carry and duty applications where the pistol may sit holstered for extended periods.

Large Viewing Window with Multi Coated Glass

The 0.95 inch by 0.75 inch viewing window provides a large sight picture for fast target acquisition without tunnel vision. Multi coated optical glass maximizes light transmission while reducing glare and reflections that can obscure the reticle or target. The open reflex design eliminates the tube effect of enclosed optics, maintaining peripheral awareness during dynamic shooting. Ten brightness settings adapt to lighting conditions from bright sunlight to low light environments, with dedicated night vision modes for use with NVG equipment.

Follow safe handling and manufacturer instructions. Ensure compatibility with your pistol's optic cut before purchase. Verify proper mounting and torque specifications during installation. Inspect optic regularly for secure mounting and lens clarity.
