Product Details
The Primary Arms GLX MD-21S AutoLive is the red-illuminated, 2 MOA variant of the MD-21S platform, combining AutoLive motion-sensing activation with Primary Arms' ACSS reticle in the GLX-tier compact 21mm housing. AutoLive activates the optic automatically when the firearm moves and powers down after extended inactivity, ensuring the sight is always ready when needed. The 2 MOA dot provides a finer aiming point than the 3 MOA variant, suiting shooters who prioritize precision over raw dot visibility at close range. GLX-tier construction delivers precision-machined housing, improved glass clarity, and repeatable adjustments that hold zero reliably across extended use and varied conditions.
