Try an extractor up-grade, such as the D-fender, to eliminate extraction problems, my AA upper was a nightmare first time at the range-same as yours, bjorn = empty brass on top of fresh round in mag., then zero extraction. I felt the need to send the upper back. A new D-fender cured that. As far as the ejector spring- cut 1.5- 2 coils-then leave it alone.
