EOTECH'S HWS (Holographic Weapon Sight) optics utilize holographic technology to greatly reduce parallax when acquiring an off-center sight picture, allowing for a point of impact closer to the sighted-in point of aim. The XPS3 series is the most compact model of HWS sights offered and comes with 20 daylight settings and 10 infrared settings. The optic comes standard with EOTECH's quick detach base, allowing for easy installation and removal with minimal POI shift. This model features an all-black finish and uses the DCR reticle. One CR123 battery is included.
