The Primary Arms GLx MD-21S Red Dot Sight 2 MOA Aimpoint Micro Footprint, Black is a red dot sight that fits Aimpoint Micro Footprint.
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.
A red dot sight lets you shoot with both eyes open and puts the aiming point on the same plane as the target, which makes target acquisition fast. Check the footprint and height suit your mount and firearm.
