Yes it does. It allows it to be fired automatically.
Allowing the recoil against your shoulder to transmit mechanical force to the trigger is no different than filing a sear pin.
Obviously.
Don’t be obtuse. Machine guns are precisely defined by law. Bump firing, either hand held or by the assist of a sliding stock do not alter the function of the weapon.
No it doesn’t.
The law defines a machine gun as a firearm that can fire more than one shot with a single pull of the trigger.
You know what a bump stock doesn’t do? It doesn’t make a firearm fire more than one shot with a single trigger pull. Bump stock equipped guns fire one shot per trigger pull. That is the definition of semi auto in the law.
Obviously.
