Someone seems to think so - news reports are rampant to the effect that every American governmental agency in existence has been stocking up on ammunition to the extent of literally millions of rounds.
Those rounds are not for revolution, but for 'food riots'.
There won't be a revolution, however as the value of the dollar plummets law enforcement will start to disappear, and anarchy will start to take place. Most groups taking up arms will be doing so simply for collective defense, although I'm sure there will be the bands of brigands about as well (many brigand groups, however, will cluster in the cities).
