I described the process required and the reason for the installation of the RS Pivot/Takedown pin on post #77 of this thread. The Pins I used, as Beach would have found through Google, is the Battle Arms Development ETP/EPP Set. They are absolutely superb by the way.
The Magazine catch was actually not Real-Steel. They are the Guarder steel Magazine catch and release button (the button is actually aluminium), and it required no mods to fit the MKM. In the photo I posted you could not actually see the allen screw on the button, as it was Photoshopped out to look more realistic.
The older pictures' B.A.D. Levers was attached to a modified Crusader Tech's B.A.D. Selector centre. It is completely incompatible with the PTS MKM, and one of my motivations to create the 45 degree ambi selector.
I do have plans to make some 45 degree selector centres to sell, but as they are quite tricky to mill, especially the 45 degree position divots, only a very limited run will be produced.
