I’m pretty sure that his ruling was quickly overturned. The restrictions are in place.
You are half correct. A stay was quickly put in place, nullifying the preliminary injunction. Two days later, the stay was nullified, putting the preliminary injunction back into place, and keeping the unconstitutional law from going into effect.
I have an article at Ammoland on those changes. I will post it on freerepublic in a day or two.
