I spent a long time setting this up to be the best performance for your buck out there, do not accept anyone trying to sell you crap Chinese lenses. I refuse to sell sub standard lenses, these are proper fujinon military glass, not generic “mil spec”, that glass quality makes a real difference in letting you utilize the full performance of the tube.

Brand new NNVT NVT4 gen2+ with fujinon glass (NVD marked,  you'll see them marked as Carson too) with an elbit battery compartment. 

So how's it cheap? China made upper shell. A plastic shell and some metal threaded rings is pretty hard to screw up, if they fit, they work, end of story. Only downside I can see to the Chinese bodies is they can't be nitrogen purged, but you weren't doing that every six months per army requirements anyway, and you arent jumping out of airplanes, so its borderline irrelevant.

It's cheap, gets you in the game, it's brand new, autogated, and white. Performance is good enough for most everyone's purposes, but obviously as a gen 2+, it'll do better in mixed lighting than gen 3, and suffer more in the darkest environments. 

I think this is the cheapest you'll see them out there,  if not,  point me to the cheapest ones.
