Like I've been saying from the start, the NRA will not allow the AR15 to be banned without a fight and made concessions in order to appease the general public after the media backlash. The NRA is the most powerful lobby in the U.S., so this is a battle the Dems know they cannot win--we'll at least not at the moment. So this is more of a moral victory than the start of gun control. Before this legislation passes, they must change the wording to include not just bump-stocks but any aftermarket modification that will allow semiautomatic assault rifles such as the AR15 to have a rate of fire similar to that of a fully automatic M16. Take for example the rapid-fire trigger. Semiautomatic assault rifles retrofitted with this mod will be able to increase their rate of fire substantially while also maintaining their accuracy. There's also the gat crank that allows a semiautomatic to fire off rounds like a gattling gun. These mods are not only legal, but much more inexpensive than bump stocks.
