The model XPS3 is EOTech's shortest and lightest HWS Night Vision-Compatible sight yet. With a single 123 Lithium battery configuration, the XPS provides additional rail space, leaving more room for rear iron sights, magnifiers or Night-Vision mount. Also, offering waterproof capability up to 33ft, the XPS3 is a great compact option for your platform. View XPS3 Operator's Manual PDF. Mfg: Eotech
