I did take a quick look,,,,,,,,,,,,,, and I and the first question that came to mind was the small plastic take down tool that was being looked at in an earlier thread, which I thought essentially did the same thing. I appologize, I can't remember whose design it was, but it seemed straight forward and portable. I don't have my R9S yet and haven't been in touch with this fine forum as much as I would like, so please pardon my ignorance on this issue.
