Was this ruling not stayed for 30 days to give the government time to appeal? Same as how every time California loses another, they get a ruling and a stay, and they get to drag the game out for eternity?
If it wasn't stayed, as I understand it, whatever district that court encompasses, just legalized full auto via case law. I suppose it doesn't address the tax stamp aspect, but a savvy resident of that district should promptly file a Form 1 for a new build MG with a copy of that ruling stapled to it, if for no other reason than to establish legal standing when the ATF denies it.
And like many in this thread already, while I don't want to use it regularly (or in some calibers, at all), if suddenly the government was told to stuff the NFA, we're actually reading "shall not be infringed" at its intended face value, I'd be pretty busy drilling third holes just because.
