I believe this is a 3x zoom Gen 2+. The image quality is actually very good on par with Gen 3 pvs14s I've used. There are only 2 slight blems that aren't even noticeable, as seen in the picture with red circles around them. Overall, in decent condition on the outside minus some damage to the mount, as seen.
The tube is great, no problems, total amount of hours I've used this is about 3 hours. This is a great piece for combloc collectors.
