Maybe outright banned in 7 states; however, not all NFA items are treated the same in every state. Many states restrict varying amounts of the items if they do not ban all NFA items. Hence, you need to look up the definition of "false" and "unequivocal" in order to use them properly.
Further, if waiting 6 to 18 months to obtain an item, that is already made, and usually displayed to you before purchase, is not lengthy, then Webster needs to be alerted. And while 18 months is based on personal experience, here's a graph showing it's within a year nearly all of the time for impartiality sake:

Let's say you get lucky, it takes 30 to 60 days to receive an item that was ready to go when you bought it (good rough ridin' luck). It's still "lengthy". The longest wait for a firearm in the country is 10 days, so minimum 300% times that is by definition, "lengthy". That word is terrible, I must stop using it.
Therefore, the windmills, or lies, however you want to characterize them, are your own.
