You are correct the AR receiver was not designed to be made of “plastic” and the C15 is not made of plastic.
The Carbon-15 receiver is made of Carbon Fiber Reinforced Plastic (CFRP). The material is plastic (def: capable of being shaped or formed) when heated. Plastic is a 100% accurate term for the receiver of the Carbon-15

Maybe you would like to point out the “massive” difference in the carbon composite used in aircraft construction versus that used in firearms.
You are the one that indicated they are one in the the same, so the onus is on you to provide the supporting evidence. You will, however, quickly find that you will be unable to, so I'll go ahead and help you out.

The injection-molded polymers used for firearm frames (which may or may not have glass or carbon fiber reinforcement in a random pattern) do not have the structural strength of the type of composites used in aircraft, which are laid up in a mold with the strands precisely oriented and precisely engineered for their specific use and the severity and direction of forces they will encounter. These composites are then compressed under heat and pressure into shape. Titanium, aluminum, or steel reinforcements may be incorporated into the material.

If you want to take the time, here is a description of the composite materials used in the F-22 Raptor:
