One more thought. IF the history of ATF rulings on auto vs non-auto for bumpstocks, an early version had a spring which allowed spring compression to continually re-fire once the trigger was pulled (one time). This would definitely fall under the automatic version, which ATF seemed at the time to so indicate. Not having a spring or other device, makes the rifle semi-automatic.
O, well 2 thoughts. As far as I can tell, any bump stock cannot actually increase the rate of fire beyond design as the trigger-sear-reset firing group activity happens still at the same speed and those are the actual limiting factors, speed-wise; the shooter's finger-rate is limited by his/her own strength, endurance and dexterity, so most likely slower than that max-rate of the design itself. Since none of those firing group pieces have been redesigned, the actual max rate of fire is still tied to them and the next shot can only occur after proper reset -- I may not have all the terminology but I think the principle here is valid.
Therefore it would be incorrect to say that a bump stock can allow an AR to fire faster than it is designed to. The real truth is that normal finger-firing is typically slower than max design rate. Anyway, I think I have that right, not being an AR expert... a bump stock may allow a person to fire faster than their normal finger-rate can but it is not beyond max rate for the AR and if their fingers/muscles were stronger they could possibly achieve that max-trigger-design firing rate...
So "increasing rate of fire" is an incorrect rationale upon which to base anything in this issue.
