Yes,
on guns that don't need extra extractor tension it can effect feeding. It can also cause the extractor to overpower the ejector and thus not allow the empty to come off of the bolt.
The bolt should really be treated as a system. When upgrading the extractor/spring/insert/0-ring also check the ejector and spring. If they feel and/or look worn....replace them.
Basically mid-length and rifle length gas system ARs don't need the O-rings/D-fenders. 5 coil springs and black inserts will work.
