HB404, titled the Hearing Protection Act, would substantially change federal treatment of firearm silencers (also called suppressors or mufflers). The bill amends the Internal Revenue Code and federal firearms law to remove silencers from the National Firearms Act definition of regulated firearms, ending the current NFA-style registration and transfer regime for silencers for persons acquiring or possessing them in compliance with federal firearms law. It also directs the Attorney General to destroy existing federal silencer registration and transfer records within 365 days of enactment.
The bill further revises federal definitions and marking rules for silencers, requires licensed importers and manufacturers to identify silencers by serial number on the primary housing or structure, and creates a new tax treatment for silencers under the excise-tax provisions of the Internal Revenue Code. It also preempts certain state and local laws that impose special taxes, marking, recordkeeping, or registration requirements on silencers, while preserving generally applicable sales and use taxes. The bill’s effective dates are generally delayed by more than 90 days after enactment.
Impact
If enacted, HB404 would repeal or narrow several federal regulatory requirements that currently apply to silencers under the National Firearms Act and related provisions of Title 18, while adding new, more limited identification and tax rules. It would affect federal registration records, transfer and making applications, and the obligations of licensed manufacturers and importers. It would also limit the ability of states and localities to impose silencer-specific taxes or administrative requirements, thereby reducing state and local regulatory authority over these devices.
Sentiment
The bill’s title and structure indicate a strongly pro-silencer regulatory approach framed as a hearing-protection measure. Because no committee transcripts or votes are provided, there is no recorded debate or vote history in the supplied materials to show broader support or opposition. Based on the text alone, the bill appears designed to appeal to gun-rights advocates and users who view silencers as safety or hearing-protection devices, while likely drawing opposition from gun-control advocates and law-enforcement stakeholders concerned about deregulation.
Contention
The main points of contention are likely to be whether silencers should remain subject to heightened federal registration and tax treatment, and whether federal law should preempt state and local silencer-specific restrictions. Supporters would likely emphasize hearing protection, reduced paperwork, and consistency in interstate commerce, while opponents would likely argue that removing silencers from the NFA weakens public-safety oversight and makes it harder to track or regulate these devices. The requirement to destroy existing federal records is also likely to be controversial because it eliminates historical registration data.
Hearing Protection Act This bill removes silencers from the definition of firearms for purposes of the National Firearms Act. It also treats persons acquiring or possessing a firearm silencer as meeting any registration and licensing requirements of such Act. The Department of Justice must destroy certain records relating to the registration, transfer, or making of a silencer. The bill also revises the definitions of firearm silencer and firearm muffler under the federal criminal code and includes such items in the 10% excise tax category.
