A little-known device called a "bump stock" is attached to a semi-automatic rifle at the Gun Vault store and shooting range Wednesday, Oct. 4, 2017, in South Jordan, Utah. Las Vegas shooter Stephen Paddock bought 33 guns within the last year, but that didn't raise any red flags. Neither did the mountains of ammunition he was stockpiling, or the bump stocks found in his hotel room that allow semi-automatic rifles to mimic fully automatic weapons.
