EOTech 557.AR223 Holographic Sight: Night Vision CompatibleThe new 557.AR223 has been developed to optimize the functionality of the HWS. The buttons have been moved from the back to the left side for instant access, allowing a magnifier, night vision, or a back up iron sight to fit closely to the HWS body. It also features a series of 1 MOA aiming dots that are vertically aligned and calibrated specifically for the ballistic drop of .223 caliber ammunition.
