ANVS, Inc offers BNS (Boresighted Night Sight) a new night vision weapon sight. Mounted in front of the existing daytime optics, BNS converts it into a fully functional night vision sighting system. All features of the daytime optics remain unchanged, including the variable magnification, reticle illumination and eyerelief. The BNS can be used with any daytime optics and almost on any weapon equipped with extended MIL-STD-1913 railing system. The system is parallax-free and requires no re-zeroing or additional boresighting. It 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.
