What is the main structural component of the GAU-2/C (7.62mm)?

• A. Receiver
• B. Barrel Assembly
• C. Fuel Housing
• D. Rotor Assembly (GAU-2/c)

Answer: (D)

The rotating rotor head is the central framework of a GAU-2/C. In this Gatling-style design, the rotor assembly carries the multiple barrels and serves as the rotating backbone that everything else attaches to—motor drive, feeds, and the bolt system are all timed and mounted around this core. The receiver is the fixed housing, not the moving backbone; the barrel assembly are the barrels themselves, mounted to the rotor; and the fuel housing is not the defining structural element of the gun. Because the high-rate fire and alignment depend on this rotating head, the rotor assembly stands as the main structural component.
