The solution is a combination of an extractor spring made from a recently declassified aerospace material that will not fail under heat and presure, and what has become known as the EXring® buffer. |
| The EXring® is a polymer ring that goes around the extractor spring, replaceing the standard blue extractor spring buffer.
The EXring® is made exclusively for Olympic Arms and is an inexpensive solution to most extraction problems. Simply place the EXring® around your extractor spring (above left), reinstall the extractor spring into the extractor . It's that simple. Using the EXring® will add tension and much needed support to the extractor and extractor spring assisting in the proper and fully reliable extraction of spent cases.
Current MSRP on the EXring®: $1.49
