A combo of all of the above, I guess.
The design seems very solid with a big beefy op rod, etc. I suppose it would be possible to crack the gas block with excessive heat or something. But, short of running the gun over with a tank, I wouldn't think there's anything inherently weak about the basic design.
The extractor, firing pin, etc are standard M16 parts so replacements and spares there are no problem. I have emailed Kevi at Barrett and have asked her about purchasing extra gas parts and will let you know what I hear.
