  If you only count those shootings with AR-15s, then yes, you have only AR-15s to count. However, if you look at the actual data collected by Mother Jones and provided in the link I gave you, the data shows that handguns indeed are used more often than any other class of firearms in mass shootings. It's not even arguable. 
  
  Toxic masculinity, anger, mental illness are but some of the causes of mass shootings. Unless you are able to block all men from acquiring firearms of any sorts then these events will continue. It's how we manage prevention, shooter isolation and intervention that will reduce the frequency of them.
