The ones I have seen have a .094" gas port on MLGS 18", which really needs to be tamed with adjustable gas, heavy spring, a heavy buffer, and often a combination of at least two of these things (heavy buffer + adj block).
As long as you go into one knowing that, you can tame the gun. I wouldn't let a .33" group at 200yds barrel leave my possession, and would just tame the gas. That's the most likely reason for your failure to extract issues. Cyclic rate is way too high on a MLGS 18" with .094" gas port. It shouldn't be over .076" really.
