Sage Flip Adapter with Nauticam CMC-1

I have been using my Saga flip adapter with a Subsee +5 and have recently purchased a Nauticam CMC-1. The adapter will not close with the CMC-1 attached. The mounting ring is not large enough. Has anyone had this issue and found a way around it?

If you purchased the CMC-1 new it should have come with an adapter ring and storage bag. the adapter ring allows it to be used with most non-Nauticam flip adapters.

Thanks, Phil. I purchased it used and it did not come with the adapter ring. I am going to message the buyer to see if he has it. Is that something that can be purchased separately?
