It mounts directly onto the figure's head, looks like this:

Quite honestly, your best bet is to buy a BBI "OWL" figure.

The night vision sight is basically impossible to find loose as is considering the age/vintage of the figure.

You can find the figure on eBay ranging in price from about $75.00 and up the last time I checked.

If you're unable to afford $75.00, then I wouldn't be expecting anyone to part with just the night vision piece for a lesser price (i.e. less than $25.00 if that).

Either go eBay or submit a post in the SWAP MEET section.

Good luck.

Good luck with your search. That was one of my favorite figures back in the day, but that nvg was frustrating to put on. The pads kept falling off; because, they didn't clip on to the frame, but were wedged on.

There was also one that was available with BBi's Tony Bishop.If that fails Dragon made some too,but not as nicely detailed.

monkeeknifefite, try contacting Ranger92, last active 9-19-2014. His site is no longer online (ranger92warriors.com) but he used to have some loose there.

Otherwise, I have some loose. Hoarded them years ago, never put to use.

From memory, the NVG's harness barely fit on anything other than the smallest of heads.

I gave one Owl night vision away a few months ago!!!!
Never liked the looks and straps all over the place.
