Yes, they are Nylon 6 with a melting point of 190 degees C. That is almost twice the temp water boils at. I think under most normal shooting conditions you would have trouble getting one that hot.
Shooting 1K rounds rapid fire as fast as you can load it will do it.

Go to 5.40 of the video.
As I said earlier I am not sure what all these torture tests prove. I can't imagine a situation where a gun owner wouldn't have the opportunity to clean his gun if he chose to do so. That and just because a gun fired 1K times in a row doesn't guarantee it will fire on the 1001 round nor more than a FTF afte two rounds means the gun will have a FTF 50% of the time.
