Featuring a large multicoated window, easy battery changes, and the widely popular RMR footprint, the Osight C Open Reflex Sight offers significant advantages for fast, eyes-open targeting. The antireflective lens coating allows maximum light transmission for a crisp image, while the choice of a 3 MOA dot, a 32 MOA circle, or both lets you customize the sight picture to the circumstances and conditions. The reticle glows at eight brightness levels for daytime use and two for use with light-intensifier night vision gear. Impact point adjusts at one MOA per click with a total range of 90 MOA elevation and windage.
Multicoated Lens
The roomy 0.95 x 0.75" window bears multiple coats of antireflection treatment, reducing glare and passing light for a sharp sight picture.
Multiple Reticle System
Switch between the 3 MOA dot, 32 MOA circle, and circle dot reticles to tailor your aiming solution to any usage scenario.
Long Runtime
The included CR1632 battery powers the sight for up to 100,000 hours with the dot reticle and 30,000 hours with the circle dot. Auto-activation and three-minute auto shutoff help conserve battery power.
10 Brightness Settings
Choose from eight daytime brightness settings and two for use with light-intensifier tube night vision equipment.
Universal RMR Footprint
Fitting directly on your optics-ready slides, the sight optic delivers wide compatibility, ensuring seamless integration across a multitude of builds.
Side-Loading Battery
Effortless battery replacement without removing the optic ensures hassle-free re-zeroing.
High-End Aluminum Alloy
A CNC-machined 7075 T6 aluminum construction makes the Osight C lightweight yet durable, and its IPX6-rated water resistance makes it useful in changing weather conditions.
