Bump sticks are ineffective as a way to increase fire rate and are a gimmick. They are notoriously unreliable. If you want to be scared, look up binaries triggers(or don’t) but they aren’t really used in crime. Other than a case here in my state, and I believe one other. Contrary to popular belief, it’s not the scary looking guns that kill most people. The majority of gun reported shootings, are suicides, or, inner city crime. Neither of which I condone by any means, however, people are not walking around with bump stocks.
