"Silencers, mufflers, sound and flash suppressors for the articles in (a) through (d) of this category and their specifically designed, modified or adapted components and parts. " are explicitly listed as Category I—Firearms, Close Assault Weapons and Combat Shotguns in Federal Law. "Title 22 → Chapter I → Subchapter M → Part 121" is the legal codification of the International Traffic in Arms Regulations.
