Its an M50.
The front two elements came out, each had their own retaining ring. The
back two elements are together in on assembly that screws on, and can be
removed with a spanning wrench. That leaves one middle element which I
cannot figure out for the life of me how to get out. I want to get it
out because I am creating a lens with only the front element.
Thanks,

I assume you mean an M or an A 50/2.0.
If so every one I've had apart the elements all come out in two 'groups',
front and rear.
That leaves just the mechanics in the assembly.
The groups can then be dis-assembled enough to get to all surfaces.
On the M lenses the front group screws out, on the A lenses the front
group is held in place with three screws.
Hope this helps.

I thought someone had posted instructions on cleaning/repairing pentax
lenses here, but I could not find it. I bought a cheap 50mm 2.0 lens
off eekbay and I cannot get the middle element out. The front two were
easy enough, and the back two came out together in one assembly, but the
middle element is puzzling. Does anyone here know how to remove it? I
dont want to take everything off the back, but it seems that there is no
option to remove it via the front.
