The Osight C is a pistol-ready open reflex optic built around the widely used RMR footprint, making it compatible with a broad range of optics-ready slides and mounting systems. Its side-loading battery tray allows battery replacement without removing the optic, helping maintain zero while simplifying maintenance.
The large viewing window and selectable circle-dot reticle are geared toward fast acquisition and easier tracking during recoil, while anti-reflective coatings improve visibility in varying lighting conditions. Available in both red and green reticle versions, the Osight C offers flexibility for different shooting preferences and environments.
