Add me to the list of those who say "Meh, what's the point?"... Don't see the appeal to carry an AR style rifle with less power. I'm not a cowboy riding the trail carrying all my ammo with me. Want to shoot the AR cheaper? Get a .22lr conversion.

Agree with those who say that if S&W thought there was a market for a 9mm AR and they could profit, they would make them. If you really want a 9mm carbine, there are several to choose from. For me, if it is just going to be a fun gun, I would just get the Hi Point carbine and call it good.
