My last trip to the range ended with about 3 fte out of the last 2 mags. That was after about 50 rounds. I stripped it cleaned it and lubed it. I remembered reading posts about the extractor screw working loose. I checked it and was able to tighten it almost a full turn! Yesterday I went back to the range and shot 100 WWB and about 25 AE FMJ with not one failure! I even fired my last two mags as fast as I could pull the trigger! I took it home and gave it a well deserved cleaning and lubing. I think I have a keeper!
