I bought a California compliant M&P 10, but I live in a state which permits suppressors. I just bought a YHP Phantom Titanium suppressor, and I was wondering if there would be any problems installing it to the rifle since it is the California version. Do I need to install anything on the rifle other then the QD mount?

Thank you.

My understanding is
The CA version does NOT change the threading of the barrel or anything.
As you will notice you have a BB (bullet button) and the ambidextrous magazine release has been cut off. Oh and you were sold a 10 rd mag instead of the 20.

That is what makes it a CA version.

I recommend selling that version and buying a normal one, or replacing the CA BB and get a new magazine release assembly that has not been messed with.

IMHO no use having an inferior weapon when there is no reason to own one.
