Stop Arming Cartels Act of 2024

HR 8427, the Stop Arming Cartels Act of 2024, bans the civilian possession, sale, or transfer of rifles capable of firing .50 caliber ammunition, with exceptions for government use and rifles already owned before the law's enactment. It requires owners of such rifles to register them with the federal government within 12 months (without fees) and adds a new provision allowing lawsuits against sellers who knowingly supply these rifles to foreign drug traffickers. The bill also expands federal firearm prohibitions to bar individuals designated as significant foreign narcotics traffickers under existing law from purchasing or possessing firearms. These changes directly affect civilian rifle owners, gun sellers, and foreign drug traffickers targeted by U.S. sanctions.
