The GLx MD-21s is a high-performance micro dot optic, built for superior agility and precision from close-quarters to intermediate range. This red dot features an advanced solar failsafe system, supplementing your power supply to ensure the optic operates with maximum runtime. On top of the solar failsafe, this red dot sight also features Autolive technology that turns the reticle off when set down for two minutes and immediately turns on the moment you pick it up.
