Mich. a full auto state
From Eric Larson, on subguns.com:
"Michigan Attorney General Cox issued Opinion No. 7183, dated December 27, 2005, which supercedes former Michigan Attorney General Frank Kelly's Opinion No. 5210, dated August 10, 1977.
Boiled down, it means that Michigan residents are legally entitled to lawfully possess NFA firearms and devices, as long as they are legally registered with ATF and ATF approves the transfer application (i.e., that the Michigan resident has no convictions that would prohibit possessing a firearm, and gets his/her paperwork signed by a CLEO or done through a corporation). Anybody who wants it should be able to obtain a copy of the foregoing Opinion by contacting the Michigan Attorney General's office.
Opinion No. 7183 clarifies that an approved application to transfer an NFA firearm or device meets the requirement under Michigan law as a "license" required to lawfully possess a machine gun. If you get the Opinion, and read it, it will answer all of your legal questions. I understand some folks are in the process of sending the Opinion to ATF to get it implemented in the National Firearms Act Branch so applications by Michigan residents will be approved. This covers all NFA firearms and devices, in addition to those classified as curios or relics."
