Let’s say that it was illegal to manufacture bump stocks. How hard would it be to make a home made bump stock without using a digital printer?
“...How hard would it be to make a home made bump stock without using a digital printer?”
The design being looked at by zillions of news customers depends on a set of molded plastic stock parts. The outside one is a sleeve that fits over the internal one, which provides the main structure. When the gun fires, the internal one moves back against spring pressure, traveling inside the sleeve, which is held immobile against the user’s shoulder or leg or something relatively solid.
As this movement occurs, the tab to the left of the trigger - an extension of the external sleeve - is moved forward in relation to the trigger, pushing the user’s finger off the trigger. Thus freed, the rifle mechanism resets.
When the rifle comes to rest, the spring pushes the internal stock forward, moving the entire rifle forward. Since the user’s hand is still in place, when the trigger clears the side tab, it is thrust against the user’s trigger finger again and the rifle (itself cycling much more quickly) fires. Cycle repeats until the rifle runs dry or the user consciously moves their finger well forward.
And cycle duration is much smaller than the interval of time in which the average mortal can deliberately move their finger.
The genius of the bump-fire stock is that the inventor packaged it all neatly and durably, and the shapes of the parts render mastery of the technique much easier than earlier devices.
All of it can be duplicated pretty decently with nothing more than a rubber band, but the technique for using one of those is trickier.
On mine it would take 18 hours or more to print a bump stock out and depending on the filament chosen and the density would cost a couple of bucks. So I would be forced to halt my production of personalized dollar store type trinkets all night and into the next day.
We have a long history of feel good type legislation in this country. Congress can claim that they did something. Then the next time someone uses a bump fire technique or device to increase their rate of fire into an innocent crowd congress can say what they did was “illegal” and it shouldn't have happened.
