Meprolight MEPRO M21 Day/Night Illuminated Reflex Sight – Battery-Free Targeting

The Meprolight MEPRO M21 Day/Night Reflex Sight delivers battle-proven, battery-free aiming capability trusted by Israeli Special Forces and tactical operators worldwide. Engineered for both close-quarters combat and extended engagements, the MEPRO M21 combines a fiber optic collector system for daytime illumination with a self-powered tritium light source for automatic night operation — no batteries, no switches, no compromises.

Built around a large 30mm diameter lens, this reflex sight offers an expansive field of view and supports both-eyes-open shooting for faster, more instinctive target acquisition in any environment. The transition between day and night illumination modes is seamless and fully automatic, ensuring optimal contrast between the aiming dot and the target at all times.

Designed to perform under extreme conditions — including adverse weather, post-exertion stress, and high-pressure engagements — the MEPRO M21 is compatible with a rear-mounted magnifying scope for enhanced precision at distance. Whether you’re outfitting a duty rifle or building a serious defensive platform, the MEPRO M21 is a top-tier optic that is always ready when you need it most.
