The  AN/PVS-22  Universal Night Sight (UNS)  is one  of  the most reliable and easiest to use night vision sighting systems.  It mounts in front of any daytime weapon sight, delivering a high quality, intensified image directly into the 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 any daytime scope it is coupled with, such as reticle illumination or variable magnification.  The AN/PVS 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 a manually adjustable gain control that allows the user to adjust image brightness (gain) to match the surrounding environment or other user-specific requirements. The AN/PVS is light weight, rugged and adaptable to almost any weapon, with a MIL-STD-1913 railing system. It is only available in one configuration with an autogated Gen 3 Pinnacle tube.   For sale only to  DOD or Federal and State Law Enforcement Agencies.
