The HWS XPS2 ODG is the non night-vision version of our shortest and lightest HWS sight so far. The CR123 lithium battery configuration of the XPS2 provides additional rail space, leaving more room for rear iron sights or magnifiers. Also offering water-resistant capability up to 10 feet, the XPS2 is a great compact and lightweight option for your platform - now in OD Green.Included in the box:HWS XPS GreenQuick-Start GuideWarranty CardCR123 BatteryProtective Case
