The attacker was on the 32nd floor of the Mandalay Bay Resort and Casino when he rapidly drowned festival-goers in bullets. Twenty-three firearms were recovered from his suite, along with high capacity magazines and 12 bump-fire stocks, or “bump stocks.”
But what in the world is a “bump stock”?
“Bump stocks” are devices that allow semi-automatic weapons to mimic automatics by allowing the user to fire more rapidly. Semi-automatic firearms require the trigger to be pulled after each shot, but with a “bump stock” attached, multiple shots can be fired after holding the trigger once.
Essentially, a bump-fire stock “bumps” the rate of ammunition fired when the trigger is pulled.
The stocks attach to the buttstock and pistol grip of an AR-15 rifle.
They also can cost as little as $50, and are legal in the United States.
However, on Wednesday, Senator Dianne Feinstein (D-CA) introduced legislation to ban bump-fire stocks.
“There is no better way to honor the 59 people who were slaughtered than to take action,” she said.
On Thursday, the National Rifle Association released a statement saying the organization believed certain modification devices, like the bump-fire stock, should be “subject to additional regulations.”
