BNS - Boresighted Night Sight
Contact
The Boresighted Night Sight
(BNS) may be the most reliable and easiest to use night vision weapon sighting system ever fielded. The BNS is a unique night
vision system that is small enough to mount in front of any boresighted daytime scope 1-12X. Similar to AN/PVS-22
and available for retail sale. Like the Universal Night Sight™, the BNS also 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.
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.
