Let’s Talk About Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt
The Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt is a high-performance upgrade designed to elevate the Ruger MK series pistol to the next level. Crafted by Volquartsen Firearms, this bolt promises enhanced reliability, smoother cycling, and improved overall performance. It’s a significant investment aimed at serious shooters looking to squeeze every ounce of potential from their rimfire pistol.
I had been experiencing occasional failures to extract with my aging Ruger MK II, particularly when using high-volume during rimfire steel challenge matches. I needed a bolt that would cycle reliably, regardless of ammunition type or environmental conditions. The promise of improved lubricity and an enhanced extractor drew me to the Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt.
Upon unboxing, the immediate impression was one of quality. The Black DLC finish gives it a sleek, almost wet look. The bolt feels substantial, yet the action is incredibly smooth when manipulated by hand; a stark contrast to the slightly gritty feel of my factory bolt.
Compared to similar aftermarket bolts, such as those from Power Custom, the Volquartsen Firearms stood out due to its integrated bolt racker and the premium DLC coating. While other options focused primarily on improved extraction, the Volquartsen Firearms seemed to offer a more comprehensive upgrade. I felt this upgrade was worth the added cost for its potential longevity and performance benefits.
My first impression was excitement mixed with cautious optimism. The bolt looked and felt like a premium component. I was eager to see if it lived up to its performance claims on the range.
Real-World Testing: Putting Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt to the Test
First Use Experience
My initial testing took place at my local outdoor shooting range, under relatively mild conditions (sunny, 70 degrees Fahrenheit). I ran a variety of .22LR ammunition through my Ruger MK IV 22/45, from bulk-pack Federal to match-grade Eley. I wanted to see if the Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt truly delivered on its promise of enhanced reliability.
The first few magazines cycled flawlessly. The extended bolt racker made manual cycling significantly easier, especially with the somewhat heavy factory recoil spring. I experienced zero failures to feed or extract during the first 200 rounds. This was a marked improvement over my previous bolt.
There were no significant issues or surprises after this first range session, only a growing sense of satisfaction. The bolt ran smoothly, cleaned up easily, and noticeably improved the overall shooting experience.
Extended Use & Reliability
After several months of consistent use (approximately 5,000 rounds), the Volquartsen Firearms MKII, MKIII or MK IV Competition Bolt has proven to be incredibly reliable. I have yet to experience a single failure to extract, regardless of ammunition type or environmental conditions. It’s a significant improvement over the factory bolt and other aftermarket extractors I have tried.
The Black DLC finish shows virtually no signs of wear, even after extensive use and cleaning. The bolt still cycles as smoothly as it did on day one. The integrated bolt racker remains securely attached and shows no signs of loosening.
Maintenance is a breeze. The DLC coating makes cleaning extremely easy. Carbon fouling wipes away with minimal effort. Compared to my previous bolt, which required frequent cleaning and lubrication to maintain reliable function, the Volquartsen Firearms bolt requires significantly less attention. It has far exceeded my expectations in terms of reliability and ease of maintenance.
