Who has got this combo running? I read about some who did but I also read the mag hight for the CMMG is slightly different.

Look at this thread: https://www.ar15.com/forums/AR-15/Thoughts-on-the-CMMG-Guard-/15-713060/?page=10
See post by 'cbecker333' he has a video link of it running in FA also.  Yes, you have to lower the block some.  
I have a local buddy using the Stern block also and did the same thing.  He also tig welded the catch in the block to engage the BHO since the entire block was lowered.
'cbecker333' also posted on page 13 using Endomags instead.
My local buddy is also running the Endomags now as well as am I.  I really like them over dealing with a mag block.

Good info, thank you. I wonder if the ATI or the Sylvan Arms blocks would do better. I would imagine they would have the same issues.

I'm really hoping the ATI magwell works. I had ordered the Stern before I knew it didn't work. In dealing with Stern I found they have shit for customer service. Hopefully something else will come along.

Let me know if you have any questions.  I'll be selling off my Stern block after I get a few more sessions with the Endomag to confirm its functionality.

The Sylvan Arms adapter does not include a LRBHO trip, so that's one issue that is moot.
