HR 4111 United States House · 119th Congress

MASS Act

HR 4111, the MASS Act, requires states to implement standardized firearms licensing systems. It mandates that individuals must hold a valid license when purchasing, owning, or possessing firearms or ammunition, with first-time buyers needing safety training. States must establish processes to deny or revoke licenses for prohibited individuals (e.g., those with domestic violence convictions, criminal histories, or extreme risk protection orders) and require dealers to conduct background checks, maintain records, and verify licenses before sales. The bill also provides federal grants to help states implement these requirements, with states needing to report on their progress.
