I ordered my M3C the day they were offered, at that time there was no foam "U" in my packaging. I did notice the close tolerance between the rear arms and the sides of the gimble when I unboxed and inspected.
I immediately cut a piece of micro-fiber material to fit over the bottom of the gimble housing to alleviate the chance for rubbing. It's a bit of a bummer that this needs to be done on a $5k unit, but that's what happens when one can't wait and Rev. 1 is your only option. I'm glad to hear they have at least admitted the oversight and provided the foam "U." At launch I did see some pictures of some units that were pretty scratched up.
