I bought a bushmaster ar 15 with a 20 barrel length but now I want to change it to a 16 ", is this just as simple as buying a 16" upper & having someone change it for me or will there be other parts I have to buy ?

  Just buy a new upper and switch them. But be aware, that if yours is a post ban gun, you CAN NOT put a preban 16" upper on it. Post ban lowers get post ban uppers. Fold the upper forward, remove the hinge pin, put new upper in place, replace hinge pin, fold back together, puch takedown pin back in, go to range.
  
  A great rifle with a junk scope,....is junk.
