Ghost ring rear sight disassembly instructions?

[fordag]

I purchased a rear Meprolight replacement ghost ring sight for my M3.  I now just need some instructions on the proper disassembly of the sight so I can replace the ghost ring.

XS big dot tritium went into the front.

There are 3 rear aperture sights for the M3; all of them are pretty straight forward.

Just unscrew the side sight screw and the sight will fall out with the spring. Drop the spring in the new sight and reverse.

Thank you.  I was hoping it was that simple.
