Ok, I did a search and found nothing on this. Someone somewhere make an adapter for the MKII take down lever. The "pin" is an allen head shoulder bolt that screws into place. Remove the shoulder bolt, and the bolt can be extracted for cleaning. No more prying that insipid little finger gashing lever! Or missing the hammer strut during reassembly. I've seen it in a catalog, and I've seen one in use, now I cannot find it listed anywhere. Grrrrr!!!
