PARTS Act of 2025
Sponsored By: Senator Tim Sheehy
Introduced
Summary
This bill would redefine 'firearm silencer' and 'firearm muffler' in federal law to cover both complete sound‑reducing devices and the outer tubes or primary housing parts that enable sound reduction when attached to a portable firearm.
Show full summary
- Gun owners and hobbyists would see more aftermarket parts and DIY assemblies fall under the federal silencer definition, which could change how those items are regulated and enforced under Section 921.
- Manufacturers and parts sellers would have standalone outer tubes or primary housings counted as silencers even if they lack internal sound‑reduction components, affecting what parts are treated as regulated items.
- Law enforcement and courts would have a broader set of items that can be classified as silencers for prosecutions and compliance reviews, because attachments and adapters that enable use are explicitly included.

Broader definition of firearm silencers
This bill would broaden the federal meaning of firearm "silencer" and "muffler." It would cover any device made or intended to reduce the sound of a portable firearm when it can attach to the gun. It would also cover the outer tube or single housing part that holds the sound‑reduction pieces, even if it attaches through a mount or adapter. More devices and parts would fall under existing federal rules for making, selling, owning, and transferring these items. Gun owners, makers, and sellers could face more paperwork and penalties if they do not follow the rules. If enacted, the change would take effect right away.
