The BNS-LR is an incredibly powerful night vision weaponsight with an impressive magnification. Big brother to the BNS, it can mount in front of any boresighted daytime scope with magnification ranging from one to twenty power.
The BNS-LR does not require any boresighting and once mounted the daysight provides the aiming point. The BNS-LR maintains boresight despite normal misalignments due to mount position errors and does not alter the sighting centerline (parallax is unchanged from dayscope). The BNS-LR also contains no beam splitter or folded optics to go out of alignment.
The BNS-LR 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 20X) and still retain the same gain (image brightness) with only a slight loss in resolution.
Optimized for medium and long-range sniper weapons including the SR-25/MK11, XM107, .338 Lapua, .308 M24, Chandler & 300 Win Mag. Effective on all weapons from carbines to .50 caliber semi-automatic and bolt action sniper rifles. The BNS-LR includes FLIR’s proprietary Shock Mitigation System (SMS), allowing the unit to be
used on weapons up to and including .50 caliber bolt-action rifles. The BNS-LR is manufactured with the highest quality Gen III Pinnacle, American Made Image Intensifiers.
