What are all the parts for an AR-10 upper?

[strider09]

If I wanted to gather up all the parts to make an AR-10 upper, minus the handguard, barrel, and gasblock. what parts would I need?
I know I would need an
1. Complete upper receiver (with the ejection port cover and foward assist)
2. Charging handle
3. bolt carrier group with firing pin

Is there anything else I would need? or is that it?
