Continuous shots rang out in Orlando that killed 49 people and injured 53 others, all came from the same gun, an AR-15.
"Once you load a round up into the chamber every time you pull the trigger it fires until it's empty," said Fox Valley Firearms owner, Nathan Oberg.
Oberg sells AR-15's at his shop. It's the same gun that was used in several other mass shootings including, Sandy Hook Elementary and the Colorado move theater.
"The gun itself is getting thrown under the bus as being to blame when any semi-automatic hunting rifle could've done the same thing," said Oberg.
He says the background check for these types of guns is the same as any other gun. You just fill out a form, answer a few questions and if the FBI clears your background check you get a gun. According to gun violence prevention advocates, they say that's the problem with the system.
"People can purchase weapons online or at gun shows without any background check," said gun violence prevention advocate, Ann Muenster.
