What took her so long? California Senator Diane Feinstein’s had almost three days, and now she’s announced the inevitable…a bill to ban bump fire stocks.

Sen. Dianne Feinstein, a longtime advocate of stricter gun control measures, introduced a bill Wednesday that would ban the sale and possession of bump-stock equipment and other devices that essentially turn a semiautomatic weapon into an automatic one. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) told reporters Tuesday that multiple bump stocks were found in the hotel room used by the shooter, who opened fire during the Route 91 Harvest Music Festival on Sunday, killing 58 people and injuring over 500 others.

Here’s the relevant language from the bill:

Except as provided in paragraph (2), on and after the date that is 180 days after the date of enactment of this subsection, it shall be unlawful for any person to import, sell, manufacture, transfer, or possess, in or af- fecting interstate or foreign commerce, a trigger crank, a bump-fire device, or any part, combination of parts, component, device, attachment, or accessory that is de- signed or functions to accelerate the rate of fire of a semi- automatic rifle but not convert the semiautomatic rifle into a machinegun.

Again, the ATF deemed bump fire stocks to be legal firearm accessories about six years ago. Feinstein’s bill would not only prohibit bump fire stock sales to the public, but would outlaw their possession. That means tens…maybe hundreds of thousands of the items would have to be turned in or destroyed. Here we go.
