What is the difference between an AR-10 upper receiver and a complete upper assembly?

An AR-10 upper receiver is the receiver component itself, while a complete AR-10 upper assembly generally combines the receiver with a barrel, handguard, gas system, and muzzle device. Depending on the individual product, the bolt carrier group and charging handle may or may not be included. Because large-frame AR specifications can vary, always verify the receiver pattern, caliber, included components, and compatibility with your lower before purchasing.
