NICS (National Instant Criminal Background Check System)

The National Instant Criminal Background Check System (NICS) is a computerized database used by firearms sellers to quickly determine if a prospective buyer is legally allowed to purchase a gun. When someone applies to buy a firearm, the seller contacts NICS, which checks records for criminal history, mental health adjudications, domestic violence restraining orders, and other disqualifiers. If there are no issues, the sale proceeds almost instantly. This system aims to enhance public safety by preventing prohibited individuals from legally obtaining firearms, while facilitating law-abiding citizens' access to legal gun purchases.
