Volquartsen 10/22® Bolt Tune Up Kit


Categories: ,


Many extraction, ejection and ignition problems with the Ruger® 10/22® rifle may be caused by the extractor or firing pin.  Now you can replace both these parts with Volquartsen’s Bolt Tune Up Kit which consists of a new EDM extractor and a SureStrike firing pin. The Exact Edge Extractor is manufactured through an EDM process to produce exacting tolerances. The new extractor will not lose its edge under impact such as other extractors made from stamped steel or titanium that will have their edges roll over and actually cause extraction problems after a short period of use. Our extractor features a very precise hook point. It is hardened to a Rc 58-60 to withstand years of use and still maintain its edge. We are able to hold the tolerances to +/-.0001″ by utilizing the EDM manufacturing process. The hook is .005″ closer to the rim of the cartridge to allow for the most positive extraction available. Made of A2 tool steel.

Volquartsen SureStrike Firing Pin is designed to minimize and/or eliminate light hits on the Ruger 10/22 (22 LR model only). The SureStrike Firing Pin is precision EDM machined from A2 tool steel. The impact section of the firing pin is then surface ground to create the optimal “SureStrike” each and every time!  This new firing pin is also .004″ wider than the factory firing pin to help eliminate side to side movement in the factory bolt.  Hardened to a Rc 56–58 to prevent any excessive wear and deformation that can be found on the factory firing pin. The hardening process on the A2 material allows for a much deeper hardening when compared to conventional case hardening.
