## Summary

**This bill would broaden the federal definition of "firearm silencer" and "firearm muffler" to cover both whole sound‑reducing devices and specific component parts.** It would amend 18 U.S.C. § 921(a)(25) to define a silencer or muffler either as a device made and intended to silence, muffle, or diminish the sound of a portable firearm and attach to it, or as an outer tube or similar single part that is the primary housing for internal sound‑reduction components and attaches to a portable firearm, including attachments that connect through mounts or adaptors that are not themselves silencers or mufflers.
