In a push to regulate ‘ghost guns,’ which are privately made firearms without serial numbers, President Joe Biden announced a ban on 'Buy Build Shoot' kits that can be bought online and assembled without a background check.
In November 2021, a 15-year-old attempted to sell a 'ghost gun' to their 16-year-old classmate at Cesar Chavez High School in Phoenix.
But the sale turned into a shooting, leaving the 16-year-old in serious condition.
