So WHY did you take apart a working sight????

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

exactly my thoughts as well.

To show how it is done.
I've had to work on quite a few that have gotten jammed up over the years.
Those T-shaped rods sometimes go askew and prevent full travel.

And some people have unknowingly bought the Chinese fakes and need help to understand what to look for to try to solve their problems.

Only difficult parts are the ball bearing and it's plunger spring on both turrets.

By the way, DO NOT open up your Swiss Products diopters.
That will void the warranty.
Those have seals.
