That's interesting, I'm trying to look up where the original manufacturer is, but even on the store page it doesn't exactly list a supplier or a brand/company.
The firearmblog write up says the QTNVG is from the "same Chinese manufacturer as the ATN PS-31 housing" -- but ATN afaik isn't a Chinese company, so I'm a bit confused.
hmm doing a bit of digging it seems like the chinese manufacturer involved is this company:
And the product in question re the QTNVG is this:
I'm a little bit confused. It seems like this company is indeed the producer of the full optics, as they're an optics company themselves?
edit, okay it seems like this company is a partner with various other companies, among them being ATN but also some bigger ones like leupold, nikon, vortex etc
Edit 2, hmm okay it seems like the tubes themselves are from elbit USA (not the Israeli elbit afaik)?
