Establishes registry allowing persons to voluntarily include names on list of individuals prohibited from owning firearm.

This bill creates a voluntary "Do Not Sell" registry managed by New Jersey's State Police. Residents can choose to register to be automatically blocked from purchasing firearms during background checks. The system verifies identities, protects privacy, notifies registered individuals' personal contacts about their status, and requires a 21-day waiting period before removing a name (with all records destroyed afterward). It does not change existing firearm prohibitions but adds a new voluntary option for residents to restrict their own access to firearms.
