So, a broken rifle is okay in "firearms" but a rifle that cannot be made to fire is an accessory. Good to know.
We use the ATF designation of what is a firearm, as well as what is a handgun (pistol), rifle, shotgun, etc. A firearm that is broken is still a firearm. When you drop off a broken firearm at a gunsmith to have it repaired, that broken firearm has to be entered into their gunsmithing bound book.
