The bill amends the definition of firearm silencer and firearm muffler in 18 U.S.C. § 921.

  • Section 921(a)(25)

    (25) The terms `firearm silencer' and `firearm muffler' mean-- (A) any device designed or redesigned, made or remade, and intended-- (i) to silence, muffle, or diminish the auditory report of a portable firearm; and (ii) to be attached to a portable firearm, directly or through a mount, adaptor, or other device that is not a firearm silencer or firearm muffler; or (B) the outer tube or other single part of any device that-- (i) provides the primary housing or is the primary structure for internal sound-reduction components designed or redesigned, made or remade, and intended to silence, muffle, or diminish the auditory report of a portable firearm; and (ii) attaches to a portable firearm, directly or through a mount, adaptor, or other device that is not a firearm silencer or firearm muffler.

    This change establishes a new and specific definition for firearm silencers and mufflers.
