Simply The BEST!
BCM quality 100%. So glad they provide these critical small parts. I know this extractor spring kit will stand up to hardcore battle abuse.
Anything BCM makes is good to go!
The upgrade kit works great. It’s a tight fit but have had no issues.
Great product. I've installed several. No extraction problems....ever!
These are the “absolute” best spring kits out there for your AR bolt!!! I’ve used several different brands, and these are the best!! They are made better and last longer than any Mil Spec I’ve ever used.
You seem to get just a bit extra with BCM parts!!!
