if you buy a rifle from a FFL it will be registered.the only state I know is Mass that registers all guns.
the gun dealer keeps the records so the gov only gets them if the dealer goes out of business.
I went back to a dealer and found out that Michigan has only the federal quicky check and with my cpl I basically signed the form and that was it. They didn't call it in and filed it the archives. Thanks for all you help.
