The possession, manufacture, or sale of a firearm silencer is permitted in Michigan under MCL 750.224(1)(b) if the person is licensed or approved to possess, manufacture, or sell such a device by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, as required by MCL 750.224(3)(c). Possession, manufacture, or sale of a firearm silencer by an unlicensed or unapproved person is a felony, punishable by up to five years imprisonment under MCL 750.224(2).

Meaning,
we can just go and buy one from a dealer/mfg with the proper credentials, and the person is approved to own one. Same 200.00 per silencer tax.
