I mean, are there any issues with extraction regarding any certain bolts, ammunition, manufacturers and so on, where it would be beneficial to use the O-ring extractor.

It's more beneficial to use it with M4 carbines, M16s and SBRs. Other alternatives are Wolff extra power extractor spring and the D-fender. Wolff website recommends their extractor spring should be used in combination with the new black extractor spring insert available from Colt. Springs are also recommended for the AR-15.

FWIW, I use the Wolff spring, by itself, using no O-ring or insert and it runs fine, including harsh use in carbine class. That's not as recommended by the manufacturer, but I'm still of the opinion that the insert does next to nothing, regardless of the color.

I have to say I have seen a time where the black O-ring does help with extraction. My bud let me borrow his AR-10, I went to the range and it failed to extract 90% of the time. I think Armalite installs one O-ring on the extractor spring from the factory, but IMO this is useless because there is so much room for travel of the AR10 extractor spring that it did not compress the O-ring.
I went to the local hardware store and picked up a second O-ring for .28$. I doubled up the O-rings on the extractor and it ran like a champ. Matt Carper |

AR10s require 2 Orings and this is a widely known fact.

Why doesn't Armalite fix this by making the necessary extra power spring instead of using o-ring band-aids?  Seriously, the fact that two o-rings are needed should be a clue!  Maybe Wolff will start making some AR10 extra power springs soon... |

Regardless of this being a widely know fact, the question was if O-rings helped with any thing or not. Matt |

Yes, as they multiply the extraction force. |

With a short gas system like a carbine, the bolt-opening timing is altered, and the bolt is attempting to open when the pressure is still high in the case.
This causes difficult extraction, and the added extraction force helps. The MGI D-Fender is a better engineered option than the O-ring, but either will work. |
