Last month, as his White House struggled to respond to the school shooting in Parkland, Fl., President Trump surprised Republicans when he said he would consider banning bump stocks, attachments that can be added to semi-automatic rifles to make them fire faster. While the Florida shooter didn’t use a bump stock, the shooter who killed 58 people in Las Vegas in November did, which is why the Department of Justice has been looking into reinterpreting the legality of the device. Now the Senate is considering a bipartisan bill to ban bump stocks, suggesting there’s a real chance they could soon be illegal to sell, Slate reports.
Just because something becomes illegal to sell doesn’t mean it will be illegal to make. Some gun enthusiasts are turning to YouTube to learn how they might 3-D print a bump stock of their own. “What kind of glue did you use to stick it all together?” asked a YouTube commenter under a video showing off a 3-D-printed bump stock in action. “Also can you explain what you did to your stock release for how to make it work? I have all the parts done and ready but need some help.” It’s not unusual for gun sales to increase after a mass shooting as consumers worry they may not be able to buy certain firearms in the future. The market for building unmarked and unserialized do-it-yourself weapons—assembled either from components you buy or ones you 3-D print—is booming. “We doubled our expected sales for the month just in the back half of February,” said Cody Wilson of GhostGunner.net, a website that sells gun components as well as a milling machine for at-home gunsmithing.
