Earlier this week, the Trump Administration, through the Department of Justice, unilaterally re-defined bump fire stocks as machine guns. The fact that the the ATF’s own earlier assessment of the stocks under current law reached the conclusion that they are “a firearm part and…not regulated under Gun Control Act or the National Firearms Act” doesn’t seem to matter. Bump fire stocks are now machine guns because the ATF says they are.

Now, however, a new product is being announced by a company called Lord Rockwell. And for now, they’re archly calling their product the Not-A-Bumpstock (that name may change).

TTAG spoke to the Not-A-Bumpstock’s inventor last night who told us that he invented this thing for a relative who was born with a deformed arm, loves to shoot, but couldn’t use a standard bump fire stock.

He said that while this product accomplishes what a bump fire stock does, it does it in such a way as to be different enough that the ATF’s latest ruling won’t apply. Details about those differences are being withheld until early January when a full rollout will happen with a press release and video that will show exactly how the Not-A-Bumptock goes about its business. For now, all we have to go on is the drawing above.

As we told him last night, we wish the enterprising inventor, who’s licensed his device to Lord Rockwell, good luck with his product. He said that he will be submitting it to the ATF for formal approval. But we certainly have our doubts.

If they ATF can waive its regulatory wand and magically designate an approved firearm part as a machine gun, it’s hard to see why another item that similarly increases the rate of semi-automatic fire would fare any better. But we’ll be watching.

Here’s Lord Rockwell’s statement:
