Olight Osight K | 6 MOA Red Dot Sight with RMSc Footprint and RMR Adaptor

The Olight Osight K is a compact, carry-ready red dot sight optimized for slimline and subcompact pistols. Featuring a bold 6 MOA dot and a direct-mount RMSc footprint, it provides rapid target acquisition and seamless compatibility with optics-ready slides. With its low weight and streamlined profile, the Osight K is ideal for concealed carry, EDC builds, and backup duty pistols where fast presentation and reliability are critical.

The 6 MOA reticle excels in defensive contexts, providing high visibility under stress and quicker alignment when drawing from concealment. This larger dot supports rapid transitions between targets without cluttering the sight picture. Motion-activated wake brings the reticle to life with the slightest movement, while a 3-minute auto-off conserves power during downtime. A low-voltage indicator flashes when battery capacity drops below 2.2V, ensuring the optic gives timely notice before replacement is required.

The side-loading CR1620 battery tray allows changes without removing the optic, preserving zero and minimizing downtime. Combined with the rugged housing and RMSc mounting footprint, the Osight K offers durability and reliability across diverse carry platforms. Its lightweight chassis preserves slide speed while maintaining recoil resistance and environmental resilience suitable for daily defensive use.

Included with this purchase is the Olight Osight RMR to RMSc Adapter Plate, which extends mounting flexibility. Precision-machined from SUS420 stainless steel and treated with a matte black PVD finish, the adapter resists corrosion and wear even under harsh use. At just 14 grams, with dimensions of 45.2 mm × 25.5 mm × 4.3 mm, it maintains optic alignment under recoil while preserving slide balance and sight co-witnessing potential.

The adapter plate is compatible with Osight optics including the K, SE, and S, as well as other RMSc-pattern models such as the 407K, 507K, and EPS Carry. Installation is straightforward with the supplied screws and torque-compatible tool, enabling quick setup and secure lock-up. Whether adapting a concealed carry pistol, upgrading a duty sidearm, or expanding compatibility across multiple hosts, the RMR to RMSc Adapter Plate ensures a stable and durable mount for RMSc-pattern optics.

Each package includes the Osight K red dot optic, CR1620 battery, mounting screws, adjustment tool, user manual, and the RMR to RMSc Adapter Plate with installation hardware. Together, they deliver a reliable, carry-focused red dot system with expanded compatibility, ready for real-world defensive and training applications right out of the box.
