Is there a certain trick to removing the lens retaining ring from the eyepiece assembly on my PVS 7A goggles? I didn't just want to pull them off and break something.
I purchased a housing that was in better shape than mine but the interior was dusty from being stored without any tube/lens assy.
The eyepieces are dusty on the interior side and I'd like to give them as well as the mirrors a more thorough cleaning than just air.
As you may know the manuals (both the Army's DS maint. manual and Litton's factory manual) recommend you pry the plastic ring off with a tool. I nearly broke mine doing that and I wouldn't recommend it. Nightline can do it for you (and they have a lot of spare parts for the 7A) and they are pretty cheap. I went with them.
