The M-16 could,I suppose,be called an “assault weapon”...because it's capable of automatic fire. An AR-15,although it might look scary (to some),isn't capable of anything that a thousand other semi-automatic rifles are capable of.

With that reasoning, the M-16 is “capable” of launching grenades as well, when configured that way. But “capable of” is misinterpreted here. The civilian M-16, generally, is not configured for full auto, and when full auto, is already strictly controlled.
