Shield Sights AMSc 4 MOA Enclosed Emitter Red Dot Sight

The Shield Sights AMSc (Advanced Mini Sight Compact) is a closed-emitter red dot sight built for compact and sub-compact carry pistols. The AMSc projects a 4 MOA red LED reticle driven by Shield's automatic brightness system, delivering fast, both-eyes-open target acquisition at defensive distances.

Shield built the AMSc around an all-aluminum housing with a crystal-clear 19mm x 16mm square all-glass objective lens. The enclosed-emitter design protects the LED from rain, debris, and pocket lint - a meaningful step up from open-emitter mini red dots for everyday carry. An integrated rear peep sight co-witnesses with the dot for a clean, intuitive sight picture on slide-mounted carry pistols.

The AMSc uses Shield's iconic RMSc footprint, making it a direct mount for the growing field of RMSc-pattern optic cuts on compact carry pistols. The light source is an eye-safe red LED with no laser hazard to the shooter or bystanders, and the optic runs on multiple battery options for flexible field swaps.

A nitrogen-sealed housing is rated submersible to 30 feet for 30 minutes, giving genuine all-weather durability with zero user maintenance. 1X magnification keeps the optic true to its purpose: fast, both-eyes-open aiming on a carry pistol.
