The AR-15 is the most popular hunting rifle in America. So much for the theory that “assault weapons are only good for killing humans.” Also, since there are approximately 20 million Ar-15s owned in the US, making that rifle the single most popular firearm in America. The AR-15 is in common use, meaning that banning it would be unconstitutional under the Heller decision.
One thing I take from the article:
Since the registry has been closed to privately held machine guns since 1986, that entire increase has to be dealer samples and police machine guns. I can’t see more than 300,000 dealer samples, so that must mean cops have greatly increased their inventories.
