I have a US Night Vision AN/PVS-14D from Northrop Grumman (Litton E.O.S.) for sale. Like new. It has been used not even for 5 min. It could be used as either a night vision scope on top of a AR15 or a light weight monocular night vision. We include both the mount for the AR-15 and head-mount and military headstrap. Generation 3+. Also, include carrying bag, manual, lenspen, and eyeguard. It is a self-contained system operating on 2AA batteries and features manual gain control to meet various brightness conditions. In addition, it contains an infrared led for short range illuminator for map reading and a red low-battery indicator appears in the eyepiece when battery replacement is needed. And more!!!!! We want $4,200.00. If you have questions or needs pics, e-mail me at email@example.com.
