The Volquartsen Competition Bolt for the Ruger MK IV is a precision-engineered upgrade for shooters who demand reliability and smooth operation. Built on the foundation of a CNC-machined design with exacting tolerances, this bolt transforms the manual cycling feel of your rimfire pistol. Whether you're running high-volume practice sessions or pushing accuracy at the range, the Competition Bolt delivers the fit and finish that makes the difference between a decent gun and one that just works.
The standout feature here is the extended bolt racker—machined directly into the bolt itself—that gives you a proper purchase when you're manually cycling rounds. No more hunting for leverage or pinching your fingers between the slide and frame. The bolt ships ready to go with Volquartsen's Exact Edge Extractor and SureStrike Firing Pin, components chosen to work in concert for consistent and reliable feeding and ignition.
Durability is built in. The bolt receives a case-hardening treatment followed by a high-performance premium finish that hardens the steel, reduces internal stress, and cuts friction without needing constant relubrication. You get improved wear resistance and a slicker action—practical benefits that add up over thousands of rounds. The black finish is as tough as it is clean-looking on your build.

The Volquartsen Competition Bolt is designed for the Ruger MK IV. If used with an MK III, the loaded chamber indicator must be removed from the pistol.
The bolt includes the Exact Edge Extractor and SureStrike Firing Pin installed and ready to use.
The premium finish applied to the Competition Bolt is lower-friction and requires much less lubrication than standard parts while offering greater wear resistance.
