A lot of the russian "night vision" sets were/are junk. The FDA briefly stopped the importation of them in the 90's due to poorly constructed laser and IR emitters that had the possibility of causing eye cancer!
A lot of companies use some russian or chinese components and some American components, cobbling them together and making up names for them. Names that usually SOUND similar to things like PVS14, such as MMS14, XYZ14. Unsuspecting buyers THINK they are getting the equivalent of a REAL PVS14 and of course they are not.
Gen II Russian is basically equivalent to mil spec FIRST GEN U.S.
For the money you are looking to spend I would suggest finding a PVS2 1st generation U.S. scope.
Two hard and fast rules for survivalists looking for night vision have always been-
1. Buy mil spec. Commercially made units are not designed to be submerged up to 66 feet, take the shock of being weapons mounted, won't take falling off the back of a tank, etc. Buy mil spec units.
2. In general you want to stick with U.S. units with a warranty to avoid parts problems later. A decent NVD is now going to have a FIVE YEAR warranty with it.
People who bought U.S. mil spec PVS4's, PVS5's 7's, etc. in the 80's and 90's are still able to find parts. People who bought russian eye blinder crappola in the 90's couldn't find their DEALERS a few months later, let alone PARTS!!!
Currently military used systems like the PVS14, PVS7's, etc. will be supported with parts easily into the next 20 years.
I will say this, having had several 2nd gen sets, I sold them all and got one 3rd generation set. I've never looked back and I've never regretted it. Saving up for more now actually :thumb:
