The AN/PVS-22 Universal Night Sight (UNS) is one the most reliable and easiest to use night vision sighting system ever fielded.  It mounts in front of any daytime weapon sight delivering high quality intensified image directly into focal plane of the sight.  The system is parallax-free and requires no re-zeroing or additional boresighting. It also retains all the features of the daytime scope it is coupled with, such as reticle illumination and variable magnification.   The UNS was designed with simplicity and reliability in mind, it contains no prisms or other complicated optical systems that can go out of alignment.  It also incorporates manually adjustable gain control, which allows the user to adjust image brightness (gain) to match the surrounding environment or other user-specific requirements. The UNS is lightweight, rugged and adaptable to almost any weapon, with a MIL-STD-1913 railing system. The AN/PVS-22 is only available in one configuration with Autogated Gen 3 Pinnacle tube.  For sale only to  DOD and Federal and State Law Enforcement Agencies.
