The 15-year-old accused of bringing an AR-15 to his Phoenix high school last week also allegedly possessed a device that would allow the weapon to function as a fully automatic machine gun, according to court documents exclusively obtained by NBC News.
The boy allegedly brought the device — known as a "lightning link" — along with a disassembled AR-15 and ammunition to Bostrom High School on Friday, according to the probable cause statement. The AR-15 was disassembled into an upper and lower receiver, the two main parts of the gun, according to the probable cause statement.
“When combining the upper, lower receiver and lightning link together they create a prohibited weapon,” it says. An AR-15 is normally a semi-automatic weapon, but the addition of the lightning link would make it fully automatic, meaning it could fire continuously without the shooter having to repeatedly pull the trigger.
