It goes around the extractor spring.

Blast me, but it is best left in a pars draw.
Use the correct color coded post in a quality spring and you are good to go. |

An oring like that has the same impact as the D-fender extractor upgrade in my rifles. I'd keep it myself.

it increases the strength of the extractor. makes the extractor stay on the rim of the ejecting cartridge to help stop jams.

That o-ring comes on LMT bolts. LMT supplies the military, they might know a thing or two about bolts. BCM bolts come the same way. These are the only two bolts I'd buy since they are the only two that are made and tested(MP/MPI) correctly.

Thanks for the pic here explaining how the o-ring fits...
I had a problem with double feeds on one of my rifles and I'm pretty sure this little product (with extra power spring) will take care of the issue –– I'll test it tomorrow. NOTE: getting the extractor pin back in with that much extra tension took much more effort. FYI: Pics of the D-Fender (similar product) and mini review are here: http://www.fulton-armory.com/D-Fender.htm |

That little o-ring solved my extraction problems I was having with my CMMG. Best part about it, I was able to find a high heat one at Home Depot so my range trip wasn't ruined waiting for parts to come in the mail.

Thanks for that, because I was about to ask if they came like that or if you had to put it on yourself as I had an Oring in the package with the BCM. I will assume that it comes with the O Ring already on it. Besides, I'm not sure I can break the thing down without losing something important. |

Ummm, the lable on the package that says "high heat". 
edit so I'm not just being a smart ass. For those reading that think they now have to run out to put an o-ring on their extractor, the purpose of it is to correct a problem. If your AR runs perfectly in its current configuration, and doesn't have any extraction problems, then it isn't really necessary. Sure you can add it as insurance, but if you aren't having issues, you don't really NEED it right now, so relax. |

I stick them in my bolts. I've never heard of them causing a failure, only fixing failures. So for a few cents, its a no-brainer.

I install this upgrade kit on every one of my ar's. It will eliminate extraction problems in most cases. One of the extreme cases was my Kel-Tec PLR-16. It holds a mil-spec ar bolt action. Well after firing a couple hundred rounds. There was numerous failures to eject. Very disappointed with this pistol at the time! 
And then the light switch turned on! 
Dude the pressure of a short barrel and gasses is so great that the extractor can not keep up. There is simply not enough tension on the rim of the cartridge to extract it. Hence the Extractor Upgrade O-Ring. Zero failures after the install.

I put one in my CMMG midlength and with the o-ring in it would not eject the casing, the extractor wouldn't let go. I posted about it here, and others replied with similar experiences. I would recommend against putting one on unless you are having malfunctions that indicate incorrect extractor tension. |

I am not so sure that it is the midlength or rifle-gas that has an issue with it, just that the carbine gas is so much more violent that there is enough additional vibration that it SHAKES the case loose. Yeah, you can scream your lungs out at me, saying that more extractor tension will fix everything, but the bottom line is that you are just trying to rip the case out of the chamber before it wants to go. So put the super duber spring in, and put an O-ring in, and make it to where you have to get out your channel locks to reinstall your extractor. And I won't say a damn thing when you are on the range, and the RO say cease-fire, and you drop your magazine, and go to eject the loaded round, and it stays stuck on the front of the bolt. The bewildered look on your face will be enough. Or there is so much extractor tension that it will not snap over the rim of the casing. Or the front of your extractor claw breaks off. Or you come online asking why after so many hundred or thousand rounds there starts to be a shiney spot on the tail of your extractor. just my thoughts on the matter. Brett |

Brett I played around with the upgrade also. That o-ring held the brass so tight it would not eject. I took the o-rings out and put them in the parts bin. That said, I believe that if the brass is given enough time to spring back after firing, there should be no need for this modification. I run Rock River 9mm buffers in my carbines and I think it aids extraction by delaying the action. I am not the expert, but I have a lot of rounds downrange with the standard springs/etc with no problems. |

I use the Crane O-rings I got from Bravo Co. and ADCO on all my ARs, rifle, midlength and carbine gas systems, it improves the extraction force, I use M16 auto BCG on all my ARs, I had no FTF problems of any kind in the several years I had used them.
On my carbine gas system only, I use the BCM extractor upgrade kit with the extra power chrome silicon material extractor spring, I'm running a M16 auto BCG and a H (heavy) buffer, YMMV. If you want to improve the extraction try it if you're willing to experiment, if it doesn't improve it or made it worst then don't use it. |
