carbon fouled gas tube after 500 rounds sounds like his rifle is a POS and he needs to re-evaluate the benefits of the lighter spring, choked gas tube, and garbage ammo he is trying to let off at a high rate.
"competition" means a lot of things... with "high rate of fire" this leads me to believe the guy aimed for a tacticool setup rather than a functional one. if dude is breaking bolts, extractors, plugging gas tubes... no need to look further other than his setup is complete dog sh*t and does not represent a typical, functional setup.
Race cars need work after every race, race guns do too. Guy should get with the program and stop complaining and just accept the fact that to be competitive, it requires a lot of work before and after a match.
