I know this subject comes up time to time but I thought I would share. From owning a couple and reading the forums I know the firestars are well liked but known to have the dreded FTE with next end jamming underneath it sometimes and the extractor is usually blamed. Well I picked up a m40 recently and yep started to have FTE with empty shell about half way out. Extractor didn't look bad and tension felt good but ordered a extractor spring from SARCO. New spring was a good bit longer than the original but I installed it anyway. 250 rnds later and still no FTE.
