There is a new element to the nation's gun control debate, coming out of the deadliest mass shooting in modern U.S. history. The gunman used a device called a “bump stock” to unleash hundreds of rounds of gunfire.

The stock modification allows the weapon to “bump” back and forth between the possessor’s shoulder and trigger-finger. They can make a semiautomatic weapon mimic a fully automatic one.

Dave Jenkins, a training counselor and instructor for the National Rifle Association, says though bump stocks are legal to purchase in New York State, it becomes illegal after the modification.

“Once you attach it to a semiautomatic rifle like an AR-15 or an AK variant rifle, then you are delving into possibly being illegal because you’re making the gun simulate automatic fire,” said Jenkins.

The National Rifle Association opposed a ban on “bump stocks” on Thursday. NRA officials believe the device should be subjected to additional regulations, and with restrictions slated to be put forth in New York State's SAFE Act regarding gun control, Senate Minority Leader Charles Schumer says outlawing the device is necessary. 

“While semiautomatics are perfectly allowed, automatics are not, this converts a semiautomatic to automatic, it should be abolished and there’s broad bipartisan support to do it in the senate,” Schumer, D-NY, said.

Schumer adds he sees the ban passing in the upcoming months.

Jenkins says it’s not the device that makes a gun unsafe, and with the recent massacre, it will be a lot tougher to be a gun owner in New York State.

“You don’t know when things are going to change and how they are being interpreted,” said Jenkins.
