The Primary Arms GLX MD-21S AutoLive represents the GLX tier of Primary Arms' red dot lineup, incorporating AutoLive motion-sensing technology that automatically activates the sight when the firearm is picked up and powers down during extended periods of inactivity to preserve battery life. The ACSS CQB reticle is Primary Arms' purpose-built close-quarters reticle design, providing intuitive holds for fast CQB-distance work alongside the precision needed for accurate shots at extended range. The compact 21mm housing keeps the platform low-profile for co-witnessing with iron sights, and the GLX-tier construction delivers a more robust, precision-machined housing compared to the SLX baseline. A top-tier red dot solution for shooters who prioritize automatic activation and ACSS reticle capability.
