Great upgrade. for your less than perfect BCG. Replace them on all your BCGs and have some more for spares.

Did your cheap BCG skimp out on quality springs? These are the best and they double as safety selector detent springs.

Every one of my AR bolt carrier groups gets one of these, and none of my friends/coworkers BCG’s leaves my garage without one installed either. When paired with the Sprinco extractor spring it eliminates a LOT of issues.
