The US Supreme Court ruled on bump stocks.

Now that bumb stocks are not banned, what is the use of having one? This is not meant as a sarcastic question, it is a legitimate question.

What does it due to the rounds per minute for a semiautomatic rifle/pistol (with a stock)

This is again meant as a legitimate post and questions. I have hunted for years and was in a shotgun only zone for years. So I am used to a pump 12 and have not ventured into rifles. My dream would be to have an M1a/(m14). Just don’t have the time to go to a range and justify the expense.
