01 · The brief
Plain-English summaryWhat this bill actually does

This bill amends federal law to ban devices and modifications that materially increase the rate of fire of semiautomatic firearms or approximate machinegun action. It prohibits import, sale, manufacture, transfer, receipt, or possession of such devices and newly modified firearms, with a 120-day effective period.

Why people may split

Progressives emphasize public-safety gains and closing loopholes

Watch point

Relative to its intended legislative type, this bill creates substantive criminal prohibitions and statutory definitions and integrates them into the National Firearms Act framework.

This bill amends federal law to ban devices and modifications that materially increase the rate of fire of semiautomatic firearms or approximate machinegun action.

It prohibits import, sale, manufacture, transfer, receipt, or possession of such devices and newly modified firearms, with a 120-day effective period.

Owners of semiautomatic firearms modified before enactment must register those firearms under the National Firearms Act within 120 days.

Passage30/100

Substantive firearm restriction with registration obligations is politically and procedurally difficult despite targeted scope and some compromise language.

CredibilityPartially aligned

Relative to its intended legislative type, this bill creates substantive criminal prohibitions and statutory definitions and integrates them into the National Firearms Act framework. It supplies timing, exceptions, and a registration pathway but relies on indeterminate standards and omits fiscal, procedural, and oversight detail that would be expected for a change that expands registration and enforcement obligations.
