What rifle? All of my rifles were lost in a boating accident.Hence... the absolute lunacy in the judges "learned" opinion. A serial number does not change the characterists of the firearm. It does not make it more lethal, convert it into something else or affect how it operates in any way.
What he's basically doing is trying to bastardize the common use test. Firearms without serial numbers are not commonly owned so the 2A doesn't apply. Well... neither are pink hello kitty painted AR's. So???? You going to go tell @solv3nt his rifle is illegal and must be surrendered to the alphabets??
Good luck with that.
