The most I've run at a time has been ~900 rounds at a range day with some friends. No malfunctions attributable to the gun at all (had one bad mag, which was ID'd early and removed from the pool - no other issues).
This is in a standard gas impingement design (Bushy M4A3).
IMHO, if it ain't broke, don't "fix" it. No matter how well designed, the fact is that the piston variants are all adding moving parts, some with close tolerances. That's adding more potential failures.
