Typically from 6.5 to 5.56 and vice versa it's just barrel, bolt, and magazine.
You will probably want a separate gas block and tube to add to the simplicity of the swap, but at that point is where most people just buy another upper receiver, complete 5.56 BCG that comes with a 5.56 Bolt and charging handle and just swap uppers.
Someone with a Larue upper will probably chime in with the specifics. Typically you don't see many people swapping barrels frequently on an upper and bolts back and forth on a bcg... I mean you can, but most just dont.
