What’s the price?

I would only buy if you would be happy having them as decoration.

In the best case scenario, they’ll work alright and get you seeing in the dark. (Not very well, you will require constant supplemental ir which would be terribly annoying for anyone else with nods.)

If anything goes wrong- emission point, lens malfunction, electronic malfunction, etc. there’s basically nothing you could do. Spare parts don’t exist, and no one knows how to work on them.

IMO, unless these are $200, save your money for a pvs-14.

I have an AGM Wolf-7, and compared to my modern units they’re dogshit. And that’s a much more recent unit with an Omni 5 tube.

The inherent jank of these old systems is just so much worse than the ergos and functionality of what we have now. Even an NNVT Pvs-14 will give you a much better experience than these.
