That's a hilarious criticism considering the case was about a specific statutory definition, and your personal rewording to reduce to 'kits' which apparently means a flat single piece of metal with a (wrong) blueprint on it is. In that case the anarchist cookbook is a kit since it includes flammable paper that could spark the fire of one of the designs inside, therefore also violates the NFA.

A kit is usually sold to make it easier to do something. In this case the kit makes it even harder to induce hammer follow than simply using the parts already in an ar. Some kit, lmao. It is scary speech on the same kind of metal plates that sometimes instead have business card type speech.
