fully automatic fire. >> reporter: the devices are made by several manufacturers. in nevada, there is no permit, t,ckground check or a waiting triod to buy one. we picked one up at this gun icked one up at thless than $200. ss the people who buy this buy it as a kind of toy. it's not a practical device. >> reporter: now, it's illegal for civilians to purchase fully automatic weapons made after on86, the year they were banned. these are widely available online, and lawmakers have nttempted to crack down, but a bill to ban bump stocks back in 2013 did not pass. anthony. >> mason: carter evans. thank you, carter. coming up next on the "cbs evening news," the president : sits puerto rico. and later, a look back at the career of rock idol tom petty. .. in jellyfish.
