The Boresighted Night Sight (BNS) is a night vision system that mounts in front of the daytime scope and does not require boresighting or re-zeroing. The BNS is lightweight, rugged and adaptable to almost any weapon which will accept a MIL- STD-1913 (Picatinny) rail and has shown the ability to withstand the recoil of 5.56 (223) and 7.62 (308) rifles. It has a very fast f/1.12 catadioptic lens and a 40mm output window (eyepiece). The unit incorporates gain control, which allows the user to lower the tube brightness (gain) to compensate for overly bright conditions or to increase the gain under extreme dark conditions.
