I was wondering if I order a kit from J&T will the upper come assembled?  Thanks in advance.

Yes, as far as I know J&Ts are assembled, but a few, like (I think) Federal Arms Corp. (FAC), are not assembled. E-mail J & T, I have had good luck with them responding to E-mails. J&T even agreed to put things together that weren't even on the web page. I know, there web page isn't as good (not as many options) as, say, Model 1 sales, but J&T can do about anything that M1S can, IF you ask.

yeah they come ready to go

Yes, J&T uppers are assembled, good people to order from also!
