What parts need to be swapped other then the upper and mags/mag block to go from 5.56 to 9mm?

I am asking since I am wanting to get a switch caliber setup on the same lower. With an RRA lower and RRA 9mm upper will there need to be changes made to the buffer or hammer? Thanks!

Ok, so I guess there is no way to just swap uppers and buffers and go to shooting huh. Damn. What mags does the colt style adapter take Kevin?
