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. In addition, this optic features fully upgraded lenses, a new ultra-bright emitter, intuitive push-button controls, and a heavy-duty mounting system. Check out the SLx 2.26" Mount if you plan on setting up your firearm for night vision shooting or you prefer a more headsup shooting position. The Red Dot Bright™ reticle can be cycled through 12 different settings and is night vision compatible for full operability in any environment.

This rifle scope is part of the mid-tier optics line called GLx. GLx brings premium technology and materials into an approachable price range.

The full ACSS-CQB reticle features three BDC dots underneath the chevron, allowing an unprecedented 600 yards of bullet drop compensation for 7.62 NATO or 5.56 NATO calibers in a compact red dot sight. Auto ranging and wind leads are also incorporated into this smart reticle. A CQB horseshoe grabs the eye instantly for close quarters shooting and also approximates the spread pattern of 00 buckshot at 25 yards.
