nah, it's .223
it's considered a handgun in the same sense that a Thompson/Center Encore is a handgun.
the end of the assault weapons ban meant we could start making them again though you could get pistol kits for Pre Ban AR receivers if memory serves me right.
some states, it's perfectly legal to carry a rifle on your person too though.
I do believe AZ is one of them...kinda like that black dude that had an AR and a pistol on his hip at some Obama rally.
in the states you can't carry a rifle, like TN for example, these offer a nice option for added firepower if you really think you'll need it or just like the piece of mind.
I'd be perfectly fine with the idea of having an AR pistol or AK pistol kept in my trunk or in a man purse...except that it hurts when something like that is swinging around and slapping my leg and knee jerk ratards are a lot harder to sell the idea of if being perfectly legal.
There was actually an instance a few months back when a man was carrying one of the draco pistols in a state park here (this was just made legal for CHL holders to carry in)
The man in question apparently now has a lawsuit on them for the way the park ranger handled it.

yes, I think the guy is a jackass, much like people that open carry into Wal-Mart....it's attention whoring at it's finest.
