JusticeM4, this would be a good thing to try, especially before chancing sending your gun back to Rguns! My Daniel Defense upper very rarely would fail to extract but it was a big problem when it happened. I replaced the extractor with the BCM kit and haven't experienced the issue since. I suppose you could also try the Crane O-ring, though I don't myself.
