Imposes criminal liability on persons who allow minors to access firearms used to commit crimes.

This bill makes adults criminally liable if a minor gains access to an improperly stored firearm (including in vehicles) and uses it to commit a crime. It raises the age of "minor" from 16 to 18, removes the requirement that the firearm be loaded, and upgrades the offense from a disorderly persons offense to a third-degree crime. If a minor uses such a firearm for criminal activity, the adult who facilitated access faces a second-degree crime charge (5-10 years in prison), and the firearm is deemed a "community gun" under existing law. The law aims to hold adults accountable for negligent firearm storage that enables minors to access weapons used in crimes.
