That’s a tube from a PSQ-20B. Notice the part# mx11769/ENVG.
Not meant for use in a normal night vision goggle, but can be adapted to be used in one I suppose, since those added bits are just glued on basically with hot glue. These have a pretty interesting gain pigtail, they do not have the four pin design you normally see. It’s basically a flex circuit that folds up against the side of the tube and has contacts similar to the +\- contacts on the PSU. If you’re familiar with how PVS-31 tubes work, these are essentially the same. The tube itself is just a 11769, as far as specs go, just average Omni VIII.
100% chance it’s stolen though. Notice it’s also being sold from fort bragg NC
ETA: here's a photo comparison between the tube on the listing vs the ENVG tube from the 23&P:
Attached File Attached File Attached FileIt's pretty clear that the "owner" removed the aluminum bracket on the eyepiece side of the tube. You can see the glue residue in the photo from where it used to be installed. That piece is specific to the AN/PSQ-20B; the tube is actually installed backwards on those devices, as in, you remove the objective lens, insert the tube, and affixed the objective lock ring with epoxy. They are not fun to work on, as you can imagine.
