Correct me if I am wrong, but from my understanding, the "universal background check" law is similar to the pistol purchase permit and therefore doesn't necessarily mean an ffl's involvement?
Now of course its a gross infringement that will hopefully be overturned in a lawsuit, or will see little to no compliance.
Michigan seems to be lacking in all fronts regarding libertarian/conservative politics and gun rights groups, I think sending requests to FPC, GOA, or NAGR to start a lawsuit in MI will be our best bet.
