Product Details
The Primary Arms GLx MD-21S is a solid little red dot that sits right where you need it without taking up much real estate on your gun. It's got a 2 MOA dot that's easy to pick up and track, and at 21mm it's compact enough for rifles, pistols, or shotguns that use the Aimpoint Micro footprint. The anodized finish is tough and won't show fingerprints like you wouldn't believe. Whether you're working with a rifle you already own or building something new, this one punches above its weight.
