GLx MD-21S 2 MOA dot

The GLx MD-21S Microdot Red Dot Sight from Primary Arms delivers professional-grade performance in a compact, rugged form. As part of the GLx series, it’s built for shooters who demand reliability in real-world conditions.

The 2 MOA red dot provides a precise and uncluttered aiming point, allowing for rapid target acquisition and consistent accuracy across varied distances. Its clean profile supports full situational awareness, making it ideal for fast-paced environments and dynamic shooting.

AutoLive® technology conserves battery by powering down when idle and reactivating instantly with movement. With a premium 7075-T6 aluminium housing, push-button controls, and compatibility with the Aimpoint® Micro footprint, the MD-21S suits rifles, shotguns, or use as an offset red dot alongside LPVOs.
