Question, and perhaps I'm just stupid, but I really don't know what the atf means by " without manual reloading, by a single function of the trigger"
I just find that rather confusing in the context of a machine gun.
Can someone explain this to this simpleton?
A semi-automatic firearm shall only be allowed to fire one round per trigger activation. No binary trigger that fires round number two on the release. This, I think is their focus.
I believe, you can have a firearm that, for example, fires a round, the bolt holds open, you load another round, then release the bolt (no trigger activation) that fires round two upon the bolt closing... (I visualize something like an AR action without a magazine). . A bolt action could be made to do this type of operation also. (Think Remington 700 slam fire, lol). A WAG as examples that can fire two rounds with one trigger pull that wouldn't be prohibited.
Is manual reloading referring to reloading the firearm or reloading the chamber? I'd think chamber.
Full auto, or burst of fire, would obviously be prohibited. .
