The BNS is a unique night vision system that is small enough to mount in front of any boresighted daytime scope. Scope magnification can range from one to 12 power. The BNS does not require any boresighting and once mounted the daysight provides the aiming point.

The BNS maintains boresight despite normal misalignments due to mount position erros adn does not alter the sighting centerline (parallax is unchanged from dayscope). The BNS also contains no beam splitter or folded optics to go out of alignment.

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) & 7.62(308) rifles. It has a very fast f/1.12 catadiopic lens and a 40mm output window (eyepiece). The BNS 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.
