A friend of mine pointed this out saying he wanted one after seeing Zombieland. So seeing the specs of a 12" barrel and overall 24" length I was thinking this sure looks like a SBR to me. Yet the site says Federal law considers it a handgun? Anyone have any insight into what exact makes a handgun, I thought the stock made it a rifle.
