The Internet has blown accessibility to weapons wide open.

Reveal reporter Matt Drange has been looking at how easy it’s been for sellers to list assault weapon parts on eBay and decided to see if he could get his hands on some using the site.

The online auction and shopping website has gone back and forth on its gun policy over the past 16 years. Check out this timeline of important events that have influenced how eBay deals with guns.

In this episode, Drange tells us what happened when he tried to order these parts online for this story, and we also look at how criminals are building their own untraceable “ghost guns.”
