The Meprolight M21 is used and trusted by militaries and law enforcement agencies around the world.

The reflex sight has a 30 mm display window that allows the user to keep both eyes open for better situational awareness. The user has five reticle options,  4.3 MOA, 5.5 MOA dot, Triangle, Bullseye, and open X. The Mepro M21 is always ready to go no matter if it is day or night or weather conditions.
