The Mepro M21 is a battery-free reflex sight with an always-on reticle. Fiber-optic collection powers the amber aiming point in daylight, while Meprolight tritium carries it through full dark. Bring the sight up and it is already lit, so there is no switch to flip and no battery to drain.
The 30 mm lens gives you a wide window on the target and supports quick both-eyes-open shooting. Choose the amber reticle in a 4.3 MOA dot, a triangle, a 4.3 Bullseye, or an open X to match how you shoot.
Built for hard field use, the housing meets or exceeds MIL-STD-810. The M21 was developed for the IDF and is in active service with the IDF and with military and law enforcement units worldwide.
