I personally remove extra power extractor springs or O rings when doing an AR15 build for several reasons:
1. The O rings, D rings, and extra power springs were band-aids trying to deal with cyclic rate issues on suppressed M4s and CQBRs because of early extraction.
2. Increased extractor spring tension causes increased resistance to going into battery and extractor snap-over.
3. In an unnecessarily-overgassed system, additional torsional forces are applied to the extractor that are made worse with additional extractor spring power.
Tame the system to increase the amount of time the bolt remains locked instead of using band-aids.
I am a fan of properly spec'd extractor springs, not imitation springs. There are differences in metallurgy, spring weight, consistency, and longevity between garbage springs and the real deal, despite what many amateurs just getting into the AR15 market will insist.
