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

This bill amends New Jersey law to hold adults criminally liable if a minor accesses an improperly stored firearm they control and uses it to commit a crime. It raises the age of "minor" from 16 to 18, removes the requirement that firearms be "loaded" for violations, and extends the law to cover firearms in vehicles. If a minor gains access to a firearm due to improper storage and then uses it unlawfully, the adult facilitator faces a second-degree crime charge (5-10 years imprisonment or fines up to $150,000), rather than the previous third-degree offense. The bill specifically targets adults who fail to secure firearms in homes or vehicles, aiming to prevent minors from accessing weapons used in crimes.
