MeCanik MO3 6 MOA Red Dot Reflex Sight

MeCanik MO3 reflex sight — a compact non-magnified optic that provides a single-point red-dot aiming reference for fast target acquisition.

This optic is built to present a clear aiming dot while allowing both-eyes-open shooting. It is intended for use on pistols and may also be mounted on shotguns or rifles where a low-profile reflex sight and an industry-standard footprint are required.

The MO3 solves quick sight acquisition and simple point-and-shoot aiming by offering a wide viewing window, a daylight-visible red dot, and features designed to extend battery life in typical carry, competition, and range setups.
