Bump stocks are officially banned the device allows semi-automatic weapons to fire like machine guns.

This comes after the 2017 shooting in Las Vegas, where 58 people were gunned down at the Route 91 Harvest festival. Nearly 1,000 other people were injured in the attack.

In December, the acting attorney general stated bump stocks fall under machine guns making them illegal.

Now, you have three ways to get rid of the devices.

Michael Knight says the ATF wants to help the community get rid of all bump stocks.

One way is getting in contact with your local ATF agent to turn them in.

You can also go online to learn how to disable them.

“There are detailed instructions to self-destroy these items,” said Michael Knight. ‘The third way is to contact local law enforcement.”

There's no way of knowing how many people own a bump stock. But manufacturers are no longer allowed to sell them.

Knight says it will be difficult to track how many will no longer be in use.

“There are three manners in which you can turn in these items,” said Knight. “The numbers are not going to be accurate in terms of how many individuals have satisfied the requirements.”

As of Tuesday, it's illegal to have a bump stock which means if you have one, you are required to disable it, hand it over to officers immediately or face the consequences.

“We are going to look at the circumstances on a case-by-case basis,” said Knight. “To determine the manner of which the item was turned in, and how we satisfy those requirements.”
