Replacement or Upgrade O-Ring for AR-15 Extractor

One of the smaller changes to most AR-15 bolts is the addition of a rubber o-ring over the extractor spring.  This little piece reduces wear on the extractor spring, and aids in consistent, reliable extraction of spent casings in your rifle.  Many AR-15 bolts these days already have an o-ring for the extractor spring.  This is sometimes called a “Crane” o-ring since it was first introduced as mil-spec.  If you need an upgrade, or just a  replacement AR-15 o-ring due to wear, this part will give you the reliable extraction you’re looking for.


  • Fits standard AR-15/M-16 Bolts
  • Manufactured to mil-spec dimensions
  • Made in the USA
