CONTENT
Senate Bill 1149 (S-2) would amend the handgun licensure Act to do the following:
-- Prohibit an individual from manufacturing, assembling, importing, purchasing, selling, or
   transferring a firearm, frame, or receiver that did not have a valid serial number.
-- Beginning three years after the bill's effective date, prohibit a person from knowingly
   possessing a firearm receiver that was a ghost gun precursor or was not imprinted with a
   valid serial number.
-- Require a person to have a license to manufacture firearms with a three-dimensional (3D)
   printer or computer numerical control milling machine.
-- Require a person who manufactured or assembled firearms or completed unfinished
   frames with the intent to sell to or manufactured or assembled more than five firearms or
   competed five unfinished frames have a manufacturers license.
-- Require an individual to notify the Michigan State Police within 10 days of producing a
   firearm and have it serialized in accordance with the bill's provisions.
-- Prescribe misdemeanor and felony penalties for violating the bill's provisions.
-- Specify that the bill's prohibitions would not apply to antique or inoperative firearms,
   transactions involving law enforcement agencies, law enforcement activities, or buyback
   programs, among other things.

   federally licensed gunsmith or other entity authorized to serialize firearms, before three
   years after the bill's effective date.
-- Require a person who moved into the State to comply with the serialization requirements
   within 90 days of moving.
Senate Bill 1150 (S-1) would add sentencing guidelines to the Code of Criminal Procedure to
make a second or subsequent violation of Senate Bill 1149 (S-2)'s prohibitions a Class E felony
against the public safety punishable by up to five years' imprisonment.
Proposed MCL 28.434c (S.B. 1149)
MCL 777.11b (S.B. 1150)
BRIEF RATIONALE
Generally, ghost guns are un-serialized firearms built from separate pieces or a kit and are
often made of 3D printed material and untraceable. According to testimony before the Senate
Committee on Civil Rights, Judiciary, and Public Safety, minors and prohibited individuals can
easily acquire ghost guns. Some believe that un-serialized firearms and ghost gun precursors
should be regulated and undergo serialization to reduce unauthorized and potentially
dangerous access to guns.

FISCAL IMPACT
The bills' criminal penalties could have a negative fiscal impact on the State and local
government. Violations of the bill would be punishable as misdemeanors and felonies of
different severity. More misdemeanor and felony arrests and convictions could increase
resource demands on law enforcement, court systems, community supervision, jails, and
correctional facilities. Misdemeanor convictions could increase county jail and local probation
supervision costs, which vary by jurisdiction and are thus indeterminate. Based on 2023 data,
the average cost to State government for felony probation supervision is approximately
$4,600 per probationer per year. For any increase in prison intakes the average annual cost
of housing a prisoner in a State correctional facility is an estimated $48,700. Per diem rates
range from $100 to $431 per day (average per diem is $135), depending on the security level
of the facility. Additionally, any associated fine revenue would increase funding to public
libraries.
Senate Bill 1149 (S-2) would have a minimal fiscal impact on State and local governments
other than the education and training of law enforcement agencies as to the requirements of
the bill, likely provided by the Michigan Council on Law Enforcement Standards within its
existing budgetary resources.
Senate Bill 1150 (S-1) would have no fiscal impact on local government and an indeterminate
fiscal impact on the State, in light of the Michigan Supreme Court's July 2015 opinion in People
v. Lockridge, in which the Court ruled that the sentencing guidelines are advisory for all cases.
This means that the addition to the guidelines under the bill would not be compulsory for the
sentencing judge. As penalties for felony convictions vary, the fiscal impact of any given felony
conviction depends on judicial decisions.
