See Faster. Shoot Smarter.

Osight C puts clarity, speed, and confidence at the center of every shot. A bright, wide viewing window accelerates your sight picture so targets pop instantly. Swap reticles to match the moment—from tight precision to fast transitions—while a smart motion sensor keeps the optic ready when you are and saves power when you’re not. Battery changes are a breeze and won’t disturb your zero. And thanks to its industry-standard footprint, Osight C drops onto a huge range of pistols and long guns without drama.

Why shooters love it

• Faster target acquisition: A larger sight window helps your eye find the dot immediately—speeding up first shots and follow-ups.
• Uncompromising clarity: Premium multi-coated glass delivers high light transmission and crisp edges, so the dot stays sharp in more lighting conditions.
• Zero that stays zeroed: Side-loading battery swaps keep the optic on the slide—no need to remove and re-zero.
• Adapt to any scenario: Choose a 3 MOA dot for precision, a 32 MOA circle for speed, or run both for the best of each.
• Fits your setup: Uses the most common pistol footprint and works with high/low Picatinny mounts for rifles and PCCs.
• Always ready, longer lasting: Motion-activated wake and auto-sleep preserve battery life without slowing you down.
