So this is a pretty cool find I picked up while in China. It's the optic from a PF-89 80mm disposable anti-tank rocket launcher. The rocket launcher was the PLA's equivalent to the AT-4 from 1989 until the early 2010s, after which it was phased out in favour of the DZJ-08. 

As far as I can tell, each 2.5x scope was boresighted to each individual rocket launcher. Since the launcher was disposable, this implies the scope was too. A weirdly expensive solution for the oversized and underfunded PLA of the 1980s to issue disposable magnifying optics for rockets, but who am I to judge?

If you were hoping to mount this on your RIS as a neat little low-power rifle optic... think again! There is no simple way to mount this to anything (unless you have an old PF-89 knocking around?) without significant modification. And even if you do, they were boresighted at the factory to each rocket, so there is no way to zero the scope. If you were working on your own rocket launcher project, or just like interesting military curios, this is for you. 

The scope housing is mostly made of plastic, probably ABS. The optic is very clear once you get your eyeball nice and snug in the rubber eyepiece, with the etched range and windage scale coming into focus only when your eye focuses on things in the distance, as a proper scope should. The sale includes the polystyrene box it came in.

As far as anyone's guess, this one was manufactured in 1996 and has only been opened once (by me) to verify that its okay. It's therefore 'new, old stock'.
