Now with an easy-to-see Green reticle, the XPS is the shortest and lightest HWS sight yet. The Green reticle is approximately 6X easier to see than red in daytime which can lead to faster target acquisition. With a single 123 lithium battery configuration, the XPS provides additional rail space, leaving more room for rear iron sights or magnifiers. Also offering water-resistant capability up to10 feet, the XPS2TM is a great compact option for your platform.
