The answer is probably not. Then why spend thousands of dollars on discounted knock offs, used, blemished or rebuilt night vision equipment that may prove to be useless?
Not all night vision equipment is created equal. Some discounted Generation 3 equipment available on the internet may be cheap for a reason.
Night vision systems consist fundamentally of two parts;
1) the core technology i.e. the image tube; and
2) the housing kit i.e. the housing and optics.
Image tubes are like diamonds – no two are the same. Film defects, excessive cosmetic blemishes, sub-standard specifications and surplus tubes that have been “repotted” with new power supplies can all lend to potential system failure. Many low priced Generation 3 night vision systems utilize image tubes that have been scrapped and/or rejected by the manufacturer and/or its distributor as being unfit for their proprietary systems.
European and/or Russian Generation 2/+ technology is not comparable to U.S. Generation 3 technology in overall performance. The latest U.S. Military contract (Omnibus VII) demands U.S. Generation 3 which is the state of the art in night vision technology.
Housing kits can be likened to a wrist watch; many are cheap Russian imitations. These knock-offs use similar nomenclature to battle proven U.S. Military specification systems but use inferior optics and substandard poorly machined materials that do not stand up to the rigors of law enforcement and/or military requirements.
Put two and two together and you have a night vision system that might look good on paper – but when it reaches the front line end user - beware! Saving a few hundred dollars per unit could cost a life. 
What to look for:
Demand only U.S. name brand, factory warranted systems direct from the primary U.S. manufacturer and/or its authorized dealers. Name brand systems include ITT Night Quest®, and Morovision Night Vision systems including the MV-14 Ultra and MV/PVS-7 Ultra. All of these U.S. Military battle proven systems utilize factory new, Generation 3, 64-72 lp/mm resolution (Typical) SELECT ITT Night Vision image tubes, full Mil-Spec nitrogen purged housings and optics and include a comprehensive manufacturer’s warranty.
Look for the manufacturer's I.D. label with serial # located on the side of the system housing. Don't accept substitutes that use similar nomenclatures such as AN/PBS-14 or NB-14.
