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 twelve 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 errors and 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 revolutionary when used with a high magnification fixed or variable power dayscope. The magnification is provided by the dayscope, which typically has much smaller optics than those associated with normal 4X or 6X night vision weaponsights. This means there is no loss in system gain or typical f/number loss associated with large optics. Variable magnification dayscopes can actually zoom in (up to 12X) and still retain the same gain (image brightness) with only a slight loss in resolution.

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 catadioptic lens and a 40mm output window (eyepiece).

Each unit comes with an Operator’s Manual, Soft Carry Case, ARMS Weaver (Picatinny) Rail Mount,
Flip Up Lens Caps, Batteries and a Lens Cleaning Kit.
