Illegal/unregistered machine gun.
Simpler example. I own a "crank-fire". You know, one of those cheap, plastic cranks that screw on to the trigger guard of a firearm. It has a cam, which pushes a piece of plastic, which is gun specific. It pushes/cams the plastic in and out 4 times per rotation of the crank. The piece of plastic pushes on the trigger = 4 shots per cycle. Lemme tell ya, you can REALLY SPIT out some rounds from a 10/22!
HOWEVER...Since this is hand driven, you are constantly moving your hand, i.e. activating the trigger multiple times. When I originally bought this rig, I thought , hey, if I attached a power drill/power screwdriver to it, I could really churn the rounds out! YOU CANNOT DO THIS. A machinegun is defined as (paraphrasing) a firearm which discharges more than one round per activation of the trigger. The moment you turn on the motor (activator/trigger), more than one round would be fired.
MACHINEGUN.
This is an old argument. I wish we could do it.
