Summary

Treats firearm silencers the same as ordinary firearms under federal law, removes a separate listing that singled them out, and states that silencers lawfully acquired under federal criminal law (Title 18) satisfy older National Firearms Act (NFA) registration and licensing requirements. It also blocks state and local governments from imposing taxes or requiring markings, records, or registration for silencers when those laws affect interstate or foreign commerce, and removes many statutory references to “silencer” or “muffler” from federal definitions and certain officer concealed-carry and penalty provisions.

• Silencers are removed from a separate federal listing and are treated the same as other firearms in the tax/definition code.
• People who lawfully acquire or possess silencers under federal criminal law are treated as having satisfied prior NFA registration and licensing requirements.
• States and localities cannot impose taxes or require markings, recordkeeping, or registration for silencers when those laws affect interstate or foreign commerce; such laws are preempted.
• Multiple federal statutes are revised to remove references to silencers/mufflers from definitions, penalties, and concealed-carry exceptions for law enforcement and retired officers.
• Most changes take effect on enactment, but the rule about transfers subject to the federal transfer tax applies only to transfers after October 22, 2015.
• The bill does not create new federal spending or create a new federal permit system, but it alters how silencers are regulated across tax, criminal, and state-law frameworks.
• The measure reduces or eliminates certain state-level regulatory and revenue authorities over silencers that touch interstate commerce.
• Changes could create legal and enforcement questions about how state and federal rules interact and about persons who acquired silencers under different regimes.
