How do you just simply drop-in an AR-10 .308cal (7.62x51) upper on to an AR-15’s (5.56/.223) stock lower?

Wouldn’t you need a new buffer tube? Trigger group?

And how do you get an AR-10’s mag box up into a much smaller AR-15’s mag well? None of mine interchange as drop-ins.

Yea I could see where that would be a problem, sorry but I do not have a lot of expertise on ARs. After the Garand and Thompson (high school) and the M-14 (college) I have not acquired a lot of hands on experience with military small arms.
