Yes, all XS frames I'm aware of have the little rubber shim bumpers in the top. I'm a little curious if there are any members who have a frame that these "fell out" of? Not to blame any of the known issues on that. I just noticed how sometimes people mount their lenses in Juliet's without the orbital rubbers. Thought same might be true with people purchasing used items on eBay. Not realizing what's up.
