What's more in common use than semiautomatic AR and Kalashnikov pattern rifles?
My worry, is "common use" going to be the new "sporting purpose"?
That's not what it says. Scalia would have said sporting use if he means sporting use. The case means "common use".
It's a simple argument, I think. What rifle would and do most people reach for when they reach for a rifle to use for self-defense? What was seen most after Katrina?
Every picture I saw, people tended to have ARs or various AK derivatives on a sling. One is "America's Rifle", the other is simply the world's most reliable rifle in dirty and adverse conditions. And there's millions of them in the hands of the people. That's your "common use" right there.
And yes, both are widely used for sport, now, too. (Thank you, Saiga!)
