Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV Review

What You Should Know About the Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV

The Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV is a small but significant upgrade designed to enhance the reliability of Ruger’s popular rimfire pistols. It’s a 25% stronger spring than the factory original, aimed squarely at eliminating common feeding issues. My own experience with a beloved Ruger Mark IV often included frustrating magazine feed malfunctions, particularly during more dynamic shooting sessions. This led me to seek out a more robust solution. The initial impression of this replacement spring was one of understated quality; it’s a precisely machined component, feeling robust and well-made, unlike some generic alternatives that might feel flimsy. I briefly considered simply using higher-quality ammunition, but that often proved to be an inconsistent fix. My first reaction upon installing this spring was one of cautious optimism, hoping for a tangible improvement in magazine performance.

Real-World Testing: Putting Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV to the Test

First Use Experience

My testing grounds for this magazine spring were primarily the indoor and outdoor shooting ranges, as well as informal plinking sessions in my backyard. The focus was on replicating scenarios where magazine feeding issues typically arise. This included rapid-fire drills, shooting from various stable and unstable positions, and using a variety of .22 LR ammunition types, from bulk pack to match grade. The installation itself was straightforward, requiring only basic field-strip knowledge of the Ruger MK IV.

The most noticeable improvement was immediately apparent: significantly fewer feeding failures. Rounds seemed to be pushed upwards more consistently and with greater authority, preventing them from tilting or jamming. Even when the magazines were fully loaded and subjected to rapid firing, the rounds presented themselves to the bolt with fewer hiccups. There was no significant learning curve; it functions exactly as a follower spring should, just with more vigor. My only surprise was how such a small component could make such a discernible difference in overall firearm reliability during live fire.

Extended Use & Reliability

After several hundred rounds and multiple range trips spanning a few months, the Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV has proven to be a remarkably durable and effective upgrade. It has held up exceptionally well, showing no signs of deformation, fatigue, or degradation in performance. The consistent feeding reliability it provides has become a staple of my shooting experience with the Mark IV.

Cleaning and maintenance are no more involved than before; the spring is an internal component of the magazine, and standard magazine cleaning procedures apply. I haven’t noticed any undue wear on other magazine components, which suggests the spring is well-matched to the standard Ruger magazine design. Compared to my previous experiences with factory springs and even some aftermarket magazine base pads that claimed to improve feeding, this spring from Volquartsen stands out for its focused efficacy. It addresses the core issue directly and successfully.

Breaking Down the Features of Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV

Specifications

This product, the Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV, is a straightforward replacement part with clear specifications. It is manufactured by Volquartsen Firearms and is made in the USA. The spring itself is silver in color and is designed specifically for the Ruger Mark IV and Ruger MK III gun models. It is listed as New condition.

The key specification here is the 25% stronger spring rate compared to the factory offering. This increased tension is crucial because it provides a more forceful upward push to the magazine follower, ensuring that each cartridge is reliably presented to the bolt face. A stronger spring combats the common issue of rounds nose-diving or failing to feed smoothly, which can be exacerbated by ammunition inconsistencies, magazine wear, or rapid firing. The direct implication is enhanced reliability, reducing frustrating stoppages during critical moments or simply making for a more enjoyable shooting session. While simple in concept, the precise engineering of this spring is what matters.

Performance & Functionality

The primary job of the SureFeed Magazine Follower Spring is to ensure smooth and consistent feeding of ammunition from the magazine into the firearm’s chamber. In this regard, it performs exceptionally well. The increased spring tension actively combats the tendency for rounds to stall or misalign, especially in the latter stages of a magazine or during high-stress shooting.

The most significant strength is its ability to eliminate feeding issues. This isn’t an exaggeration; my Mark IV, which previously had occasional feeding failures, now cycles rounds with far greater regularity. The weakness, if one can call it that, is that it’s an internal component. You don’t see it once installed, and its effectiveness is only apparent when the firearm is in use. It meets and exceeds expectations for its intended purpose, offering a noticeable uptick in reliability for a very modest price.

Design & Ergonomics

From a design perspective, this is a functional component rather than an ergonomic one. The Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV is a simple coil spring, precisely manufactured to fit within the Ruger MK IV magazines. The build quality is excellent; it feels sturdy and is clearly made from quality materials that resist corrosion and fatigue.

There’s no ergonomic consideration for the user because this spring is internal to the magazine. Its design is purely about mechanical function. The silver color is standard for such components and doesn’t impact performance. The true “ergonomics” are experienced indirectly through the smoother operation of the firearm itself – less fumbling with malfunctions means a more comfortable and enjoyable shooting experience overall.

Durability & Maintenance

As an internal magazine component, the durability and maintenance of this spring are inherently linked to the magazine itself. Based on my extended testing, this Volquartsen Firearms spring is built for longevity. It’s constructed from materials designed to withstand repeated compression and expansion cycles without losing its spring rate.

Maintenance involves standard magazine cleaning. When disassembling the magazine for cleaning, one should be mindful of the spring and follower, ensuring they are reassembled correctly. There are no special care instructions beyond treating the magazine and its components with standard firearm maintenance practices. Potential failure points are minimal, provided the spring is not physically damaged during installation or disassembly, which is unlikely given its robust nature. Its durability suggests it should last for thousands of rounds, significantly outperforming a worn-out factory spring.

Accessories and Customization Options

This product, the Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV, does not come with any accessories, nor does it offer direct user customization. It is a single, specific replacement part designed to fit a particular firearm magazine system.

However, it pairs exceptionally well with other aftermarket magazine enhancements. For instance, Volquartsen Firearms also offers improved baseplates for Ruger MK IV magazines. Combining this stronger spring with a better baseplate can create a truly upgraded magazine that feeds flawlessly. While this spring itself isn’t customizable, its compatibility with other enhancements allows for a comprehensive magazine upgrade.

Pros and Cons of Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV

Who Should Buy Volquartsen Firearms SureFeed Magazine Follower Spring for Ruger MK IV?

This magazine follower spring is an ideal purchase for any owner of a Ruger Mark IV or MK III pistol who has experienced feeding issues or simply wants to ensure maximum reliability. It is particularly beneficial for those who use their pistols for activities where consistent feeding is paramount, such as competitive shooting, training exercises, or even casual plinking where malfunctions can be a frustration. It’s also a great choice for handloaders or those who use a wide variety of .22 LR ammunition, as the stronger spring helps overcome potential ammunition-related feeding problems.

Those who should probably skip this product are individuals who have absolutely zero feeding issues with their stock magazines and are completely satisfied with their current reliability. If you own a very early production MK IV that has been flawless or primarily use premium, consistently feeding ammunition with no issues, this might be an unnecessary upgrade. However, given the commonality of rimfire magazine feeding quirks, most owners would likely benefit. A must-have accessory to complement this spring would be an improved magazine baseplate, as mentioned, which can further enhance grip and make disassembly for cleaning easier.
