Ok gotcha. But people would point out how fucked up it was that these things were on the market only to be told they weren't an issue because they were impractical. What I misunderstood is that they only meant impractical to hobbyists, not spree shooters firing into a crowd of people.
There has been a noticeable uptick in devices meant to give the finger to NFA rules in recent years, partly due to ATF apathy. Bumpfire stocks, binary triggers, and 'pistol braces' that are essentially just stocks that have a provision to fit on your wrist that let you buy a rifle in a pistol length, but shoulder it for more accurate fire. Once the ATF issued a letter that you can shoulder these devices legally, nearly every manufacturer started pumping out 'pistols' that are actually full size rifles with short barrels. These would normally qualify as SBRs under the NFA, but gun makers found a way around it with a complicit ATF.
The ATF can cut down on 99% of this bullshit by re-clarifying the rule that says one pull must equal one shot. The literal interpretation of this being that it's okay if a device bounces the gun around so it goes automatic, so long as it pulls the trigger each time. Or, for binary triggers, firing on the
release of the trigger, not the pull, effectively doubling the fire rate.
Never underestimate the willingness of nutters to pursue devices which clearly are meant to skirt existing laws. Most gun channels will whine openly about the NFA and how unconstitutional it is. That's how you know it works. This shooter couldn't secure legal automatics so he had to use cheap devices to do it. Enforce the laws.
