I have a used ATN viper gen 1+ goggle. Unit is in good condx with light scuffing oh headgear mounting dovetail. Unit comes with scope, headgear, orig. box, and manual I paid 270.00 and I am asking 150 firm + 13 dollars usps priority insured. I would also trade straight across for an etx 60/70 w/autostar in good working order. Bear in mind that this is not like a gen3 military goggle. This is a rugged little good quality gen 1 unit with a fairly bright (for gen 1) and high resolution tube. It works well with infrared illumnation (it has an illuminator) but it will not give you those fantastic gen3 military images like seen on cnn.
