Open bolt carbine upper?

[Patriot]

Anyone know where to get a 9mm open bolt carbine upper for a Georgia Mac10 ?

I'd like one w/ a fake supressor shrouding the barrel if possible.

Upper doesn't matter. Only difference is if you have an open bolt and get a sidecocker upper the cocking handle won't neccesarily stay open with the bolt. You use your original/the same bolt carrier as you had before you put the carbine upper on.
