(1) A person shall not make, manufacture, transfer, or possess a short-barreled shotgun or a short-barreled rifle.

(2) A person who violates subsection (1) is guilty of a felony punishable by imprisonment for not more than 5 years or a fine of not more than $2,500.00, or both.

(3) Subsection (1) does not apply to a short-barreled shotgun or short-barreled rifle that is lawfully made, manufactured, transferred, or possessed under federal law.

(4) A person, excluding a manufacturer, lawfully making, transferring, or possessing a short-barreled shotgun or short-barreled rifle that is 26 inches or less in length under this section shall comply with section 2 or 2a of 1927 PA 372, MCL 28.422 and 28.422a.

(5) A person who possesses a short-barreled shotgun or short-barreled rifle that is greater than 26 inches in length under this section shall possess a copy of the federal registration of that short-barreled shotgun or short-barreled rifle while transporting or using that short-barreled shotgun or short-barreled rifle and shall present that federal registration to a peace officer upon request by that peace officer.

(6) A person who violates subsection (5) is responsible for a state civil infraction and may be fined not more than $100.00. A short-barreled shotgun or short-barreled rifle carried in violation of subsection (5) is subject to immediate seizure by a peace officer. If a peace officer seizes a short-barreled shotgun or short-barreled rifle under this subsection, the person has 45 days in which to display the federal registration to an authorized employee of the law enforcement entity that employs the peace officer. If the person displays the federal registration to an authorized employee of the law enforcement entity that employs the peace officer within the 45-day period, the authorized employee of that law enforcement entity shall return the short-barreled shotgun or short-barreled rifle to the person unless the person is prohibited by law from possessing a firearm. If the person does not display the federal registration within the 45-day period, the short-barreled shotgun or short-barreled rifle is subject to seizure and forfeiture in the same manner that property is subject to seizure and forfeiture under sections 4701 to 4709 of the revised judicature act of 1961, 1961 PA 236, MCL 600.4701 to 600.4709.

Straight from the state police. 

Yes. If the short-barreled rifle is registered as a pistol in Michigan (because the firearm has an overall length of less than 26 inches), it is legal to carry the short-barreled rifle concealed with a valid CPL.

Quoted:
Less than 26" is the catch. Very few SBR's can make this happen. Folding stock SBR's and SBR's with 10.3" or shorter barrels have a chance. All others will be too long even though they are registered as pistols under Michigan law.

A bit off topic, recently I've been thinking about un-built receivers I bought and registered as pistols prior to the 2013 definition change.

Did they need to be operational at that time to be grandfathered?
