Meprolight MPO-S Red Dot Sight 3/33 MOA Bullseye RMSc Pistol Optic

The Meprolight MPO-S is a compact, open-emitter micro red dot sight built for optics-ready slim-frame pistols that use the RMSc/JPoint mounting pattern. Its low-profile Black housing keeps weight and bulk to a minimum while delivering the durability expected of a duty-grade carry optic. The illuminated reticle is rendered in red.

At the heart of the MPO-S is a user-selectable 3-segment reticle: a precise 3 MOA dot for fine work at distance, a 33 MOA bullseye that combines the dot with a ring, and a full 33 MOA ring for fast, instinctive target acquisition. Shooters can switch between reticle options on the fly without leaving the optic. Brightness is managed by automatic or manual control across 10 daylight and 2 night-vision settings, with full NV compatibility for use behind a clip-on or helmet-mounted device.

A single CR1632 battery powers the MPO-S for an estimated 20,000+ hours at the medium brightness setting, and Meprolight's shake-awake function conserves battery life by waking the optic on movement and putting it to sleep during inactivity. The MPO-S is a strong fit for everyday-carry, home-defense, and competition pistols that accept the RMSc footprint.
