The Bravo BCG has an extractor o ring separate from the bolt in the package. Is this an extra, or does it need to be installed?
Thanks

It's included in case you are having extraction issues and need even more extractor tension than what the 5 coil spring provides. Usually for SBR's with more violent gas systems.
