M21

The Meprolight M21 Self-Illuminated Reflex Sight is a mil-spec optic designed for professional law enforcement and military operators who require reliable performance without the need for battery power. This reflex sight is ideal for carbines, rifles, and duty weapons where performance is critical and equipment failure must be minimized.

The M21 utilizes a hybrid illumination system that combines fiber optic technology for daylight use with tritium self-illumination for low-light conditions, ensuring visibility without the need for batteries. The fiber optic collector captures ambient light, providing a clear reticle during the day, while the tritium phosphor illuminates the aiming point in darkness, although the effectiveness of tritium will decrease over time.

This sight is particularly beneficial for duty personnel, tactical teams, and military units operating in environments where battery resupply may be unreliable. Its compact and lightweight design, weighing 1.14 lbs, ensures minimal mounting offset while maintaining the optical clarity required by professional shooters in high-stress situations.
