Osight K [green]

This red dot (green) uses the Shield RMSc footprint standard.

Confidence When Every Second Counts

Osight K is built for speed, clarity, and reliability—especially when the pressure is high. A bold 6 MOA dot makes target acquisition instinctive and lightning fast, so you can trust your shot when it matters most. Compact and lightweight, it fits seamlessly onto RMSc-ready slides, while a motion sensor ensures the optic wakes the moment you move. Battery changes are effortless and won’t disturb your zero, keeping you focused on performance instead of maintenance.

Why shooters love it

• Stay zeroed, stay ready: Side-loading battery swaps mean no need to remove the optic or re-zero.
• Fits your carry gun: RMSc footprint ensures direct fit on a wide range of optics-ready slides without adapters.
• Always awake when you are: Motion-activated technology powers the sight on instantly and conserves energy when idle.
• Never be caught off guard: Low-power indicator flashes so you know when it’s time to replace the battery—before it fails.
