Osight K RD 6 MOA Open Red Dot Sight, Black

Osight K RD Features and Performance

The Osight K RD is a compact open reflex pistol optic built for shooters who want a simple, fast-acquiring red dot for concealed carry, everyday use, and slim handgun setups. Designed around the RMSc footprint, this optic mounts directly to many optics-ready slides while keeping a low-profile form factor that works well on subcompact and micro-compact pistols.

One of the standout features of the Osight K RD is its bold 6 MOA red dot. That larger dot is designed for quick presentation and faster visual pickup, which makes it especially useful for defensive carry and other high-speed shooting situations. With parallax-free performance and unlimited eye relief, it is built to support fast, natural target acquisition.

The Osight K RD also includes practical features that make it easy to live with on a working handgun. Its side-loading CR1620 battery allows battery changes without removing the optic, while the motion sensor function helps wake the sight with movement and conserve power when idle. With up to 63,000 hours of runtime and 8 daylight plus 2 night vision settings, it offers useful long-term performance in a compact package.

Built from 7075 aluminum and rated IPX6 water resistant, the Osight K RD is designed for dependable everyday use without adding unnecessary bulk. Its compact size, light weight, and RMSc footprint make it a strong option for shooters looking for a streamlined carry optic with a bold red aiming point.
