Osight K-RD 6 MOA Red Dot RMSc Open Reflex Sight - Matte Black

The Osight K-RD is a micro open reflex sight built for concealed-carry and duty handguns, packing a fast, easy-to-acquire 6 MOA red dot reticle into a slim, subcompact housing. The large dot is designed for quick target pickup under stress and works well on slide-mounted carry pistols, making it a strong match for everyday defensive use.

Machined from 7075 aluminum for a lightweight, hard-use package, the K-RD ships in a matte black anodized finish with an RMSc footprint that drops onto optics-ready subcompact and compact pistol slides cut for the Shield RMSc pattern. It runs on a single side-loading CR1620 battery, so you can swap power without removing the optic from the slide and re-zeroing.

The optic offers 10 brightness settings - 8 daylight levels plus 2 night-vision compatible settings - giving you reliable performance across lighting conditions. A built-in light sensor detects ambient conditions to assist with power management, a motion sensor wakes the optic on movement to preserve battery life, and the side-loading tray makes battery replacement a no-rezero task. The optical path is parallax-free at 1x for instinctive close-range aiming.

Compact and tuned for subcompact RMSc-cut slides, the Osight K-RD pairs cleanly with today's most popular micro-compact and compact carry pistols for fast, accurate defensive shooting.
