Building a complete upper? You will need the following: Barrel, Receiver, Charging Handle, Bolt Carrier Group, Handguard System, Gas Tube and Gas Block. Muzzle devices are optional, but usually desired. Add $25 to the barrel for muzzle threading and add $25 to assemble a complete upper with your specified barrel and parts.
