What is NICS primarily used for concerning firearms?

The NICS, or National Instant Criminal Background Check System, is primarily utilized to determine firearm purchase eligibility. Established as a part of the Brady Handgun Violence Prevention Act, NICS serves as a crucial tool for ensuring that individuals who attempt to purchase firearms do so legally. It checks various databases that include criminal records, mental health history, and other relevant information to ascertain whether a buyer falls within prohibited categories, such as felons or individuals with restraining orders related to domestic violence.

This system is vital for maintaining public safety by preventing firearms from being obtained by those deemed a risk to themselves or others. The focus on eligibility specifically aligns with the intent of gun control measures that aim to reduce gun violence while still allowing lawful citizens the right to bear arms. By processing background checks almost instantaneously at the point of sale, NICS plays a central role in the firearms transaction process.
