I've been chasing an FTE issue that just wont quit. I've installed the new extractor, spring and plunger but I'm still getting as many as 3 FTEs per 100 rds. I saved the brass that FTEd and the extractor marks are very light. I love the way this gun shoots, but the reliability issue is wearing my patience thin. Any ideas? I've been emailing Jeff at SAI but it takes him about a week to reply.
