Shield Sights AMSX Features The Shield Sights AMSX Advanced Mini Sight uses an enclosed emitter design housed in a rugged aluminum body protecting the internal optics from debris moisture and the daily wear of holster carry. A glass lens delivers a clear sharp dot free of the distortion sometimes seen in polymer lensed reflex sights. The enclosed design also allows for co-witnessing with standard iron sights giving the shooter a reliable backup aiming option if the dot ever fails or the battery runs low. Automatic brightness adjustment continually reads ambient light and sets the dot intensity accordingly so the shooter never has to stop and manually adjust it mid-string. Shield s signature footprint is one of the most widely supported mounting standards on the market letting the AMSX bolt directly onto a wide range of factory optic-ready slides from leading pistol manufacturers with no adapter plate required. The 8 MOA dot is large enough for fast target acquisition at close range while still precise enough for accurate hits at distance. A battery life rated up to 20 000 hours on a single CR2032 or 2032/2025/2050 compatible cell means the sight is ready to go for years of regular use. At just 1.2 oz and finished in a durable black anodized coating the Shield Sights AMSX is for sale at GrabAGun for shooters who want a dependable low maintenance enclosed red dot for their carry or duty pistol.
