Why the model tagged it this way: The bill primarily restricts firearms by expanding the machinegun definition to cover convertible pistols with pistol converters (banning their manufacture/sale/possession), prohibiting dealer sales of such pistols, and requiring industry members to prevent converter use. It also updates industry liability standards to include converter prevention. A narrow exception for roster listing of modified pistols is neutral as it maintains existing safety testing rules without altering access.
