Well sort of. Here is what ATF says. Basically, the bump stock is now classified under the NFA as a machine gun and owners must either turn them in to LE or destroy them.

The reclassification to a machine gun is why so many of us squawked. Its a freaking piece of plastic that in and of itself does NOTHING. It by itself cannot shoot anything. Only until you connect it to a semi auto rifle does it become anything else. Its still not a machine gun or any kind of a gun until that happens, and even then its not a gun, its an enhancement. A belt loop and thumb can accomplish the same thing.
I think it was misguided from the beginning and I sent several emails to the president voicing my concerns. As I have said before, I didn't own one, nor did I ever want one, still don't. I just fear that if ATF can just rule something to be what it cannot be is dangerous precedent.
I think eventually SCOTUS will rule it unlawful to do so, but it could be a while.
Trump succumbed to the "do something" disease on this and I believe it worked politically, but I wish he had not just let ATF make up a new rule on it. Its absurd.
