The shooters in the Buffalo and Uvalde massacres were both 18, and legally purchased assault rifles. This is fueling calls to raise the age when someone can purchase this weapon from 18 to 21.
============================================
You could reasonably ask if ‘Are 18-year-olds mature enough to buy AR-15s’, but are even 21-year-olds, un fact anyone who isn’t under the arm of the military.
For does an individual really need a machine gun of any nature.
