Volquartsen Firearms specializes in rimfire precision and performance, offering both its own complete firearms and enhanced components that customers can use to soup-up other companies’ designs, and the Competition Bolt for Ruger’s Mark IV pistol is a prime example of the latter.
Incorporating a number of improvements over the factory bolt, the CNC-machined Competition Bolt includes Volquartsen’s Exact Edge Extractor, SureStrike Firing Pin and Recoil Rod (with three recoil springs included to fine-tune to a specific load) for worry-free reliability, and the integrally machined Extended Bolt Racker ensures no more pinched fingers.
The bolt has also been given a glossy black DLC finish that not only looks great but increases hardness and lubricity while reducing stresses and friction as it cycles—and a gold-colored version with a titanium nitride finish is also offered.
The suggested retail price is $305. For more information, visit volquartsen.com.
