Michigan law 750.224 bans automatic weapons, suppressors, billy clubs, and a number of other things. This same law provides an exception in section 3(c) where you may own these items if properly licensed by the federal government.
Michigan law fails to define what "licensing" means.
As far as the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) is concerned all you need to do is file and get approved BATFE form 5320.4 to own any item restricted by the National Firearms Act (NFA).
The Michigan Attorney General issues opinion 7183 stating that in Michigan, approval of BATFE form 5320.4 constitutes a license... for a "machine gun". If form 5320.4 approval is a license for an automatic weapon, then why is it not a license when it is approved for other NFA regulated items?
We are asking that the Michigan Attorney General issue an official opinion regarding the other “restricted” items banned by MCL 750.224 indicating, that if an item is properly registered by the BATFE, it is considered to be licensed in the state of Michigan. We are also calling upon the Michigan state legislature to update Michigan's law to recognize the federal authority of the BATFE and NFA registration as legal licensing in Michigan.
