204's arent really known to be barrel burners, even with the velocity. so unless they shot the living daylights out of it...

good news is.. even if the barrel is smoked, you can get a replacement shaw barrel for around $300 or a little under. ar15parts has them in stock in both 20 and 24" lengths.
