AB night vision RNVG housing, Fujinon/Carson optics, NNVT gen 2+ white phosphor tubes with auto gain, irises and sacrifical lenses. All components are brand new, no blems or issues whatsoever. The unit was built by Carlough Manufacturing, and everything is still within warranty. Maybe 10-15 hours on the unit from a couple shoots and hikes. Will send spec sheets on request. $4000 firm, no trades unless you have a mono with a L3 supergain tube.
