The Shield Shight Advanced Mini Sight AMS Reflex Red Dot sight features a crystal-clear hard dip coated acrylic lens for a crisp, clear sight picture so you can easily see the bright red 4 MOA red dot for superior accuracy and precision in virtually any target-rich environment. Plus, the lightweight housing is machined from aircraft aluminum for a durable yet modern look. Even better, this optic has a side battery compartment for easy battery replacements even when mounted to a firearm. If that's not enough, the AMS red dot utilizes Shield's patented mechanism that enables co-witnessing with standard iron sights. Twelve stage user-controllable brightness adjustments (9 daylight, 3 night vision compatible) and 3 stage auto brightness adjustment allow users to adjust to their environment.
