post pics
just got mine and it wobbles and it's crunchy

in this picture you can see the small pin that I wrapped in Teflon tape. I used about 1 inch peice of tape, put the pin in the center and rolled it the length of the tape. Then I cut the tape on one side and slide it in the spot without the threaded section in.

the female threaded post (where the magnet screws into) I applied some grease (not to heavy) then slide the threaded section back one.

once I put that section back together, I cut the excess Teflon tape from the pin. Side the threaded section up and down a few times to get the grease worked in. The I soaked a q tip in some isopropyl alcohol to clean up left over grease.
You might have to do the tape part a few times to get it to fit right and take away the fire button twist/wobble. The grease helps the magnets move way easier because the top magnet (battery side) pushes down which slides the thread section up and down making it really smooth.
Let me know what ya come up with!
