You might give US Machine Gun a call if you are thinking of getting an upper. They might sell you an unbarreled upper or have it listed somewhere I didn't see.

Have fun.
Ah-diddn't think of that!Good idea!!
The price of a barreled upper isn't too bad-I'll wait untill I move out there before I buy one.Allthough on my reciever it doesn't say pistol or carbine on it -so technicaly I can put it on my pistol permit.
I dont know though since if I do have a carbine upper for it I might not be able to.
