The bill aims to regulate the possession and use of pneumatic guns in Michigan, particularly focusing on individuals under the age of 18. It stipulates that minors are prohibited from using or possessing pneumatic guns outside their home unless they are accompanied by an adult over the age of 18. Violations of this regulation would result in a misdemeanor charge, which could lead to a maximum penalty of 90 days in jail, a fine of up to $500, or both.

Additionally, the bill defines a "pneumatic gun" as any device designed to expel a BB or pellet using spring, gas, or air mechanisms. This definition clarifies the scope of the regulation and ensures that the law is applied consistently to all relevant devices.
