An (original) m-80 was an actual military detonation simulator that used something around 4-5 grams of flash powder. People still make them in those size as well, be it just some guy in his shed, Indians on a rez, or organized groups with cartel connections to buy the perchlorate and aluminum powder in bulk.
In addition to that, the chinks will ship fireworks cakes full of m-80's that a wholesaler in the know will order, then tear apart and sell individually.
They're just oversized firecrackers is all.
