Key Points
- Would ban devices and parts meant to make a semi-automatic gun fire much faster, including items that mimic a machinegun’s firing speed.
- Would also ban owning or selling a semi-automatic gun that has been modified to fire much faster or act like a machinegun.
- After the law takes effect, people would have 120 days before the ban applies to importing, selling, making, transferring, receiving, or possessing these items.
- People who already legally own a gun modified this way before the law is enacted would have to register it, then could keep it if it stays registered.
- The ban would not apply to guns and equipment handled under the authority of federal, state, local, or Tribal government agencies.
