Legislative Progress
Key Points
- Would ban most people from importing, making, selling, buying, or owning rifles that can fire .50 caliber ammo, with an exception for government agencies.
- People who already legally own a .50 caliber rifle before the law takes effect could keep it, but they would need to register it within 12 months of the law being enacted.
- Adds a new legal path to sue gun sellers or makers if they knowingly sell or transfer guns in deals tied to certain major foreign drug trafficking restrictions.
- Blocks firearm sales to certain foreign drug traffickers named by the President or designated by the Treasury Department, and updates background-check systems to help enforce this.
- Expands federal reporting so gun dealers must report certain “multiple gun sale” transactions involving rifles, not just handguns.
