Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine Review

The Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine: Is It Really That Good?

As a gear and equipment specialist with over a decade of experience across diverse environments, I’ve learned to appreciate the subtle nuances that separate functional components from truly reliable ones. My search for enhanced magazine capacity for my Ruger Mark IV 22/45 Lite led me to the Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine. These magazines are specifically designed for the Mark IV series, promising seamless integration and the standard Ruger quality I’ve come to expect. My previous magazines, while functional, were showing their age, and the desire for a fresh set, especially a two-pack to maximize range time, prompted this acquisition.

Upon receiving the magazines, my initial impression was one of solid construction. The blued steel felt robust, and the overall finish spoke of a product built to withstand regular use. I had briefly considered aftermarket options, but the peace of mind offered by OEM parts, particularly for something as critical as a magazine, typically outweighs minor cost savings. This two-pack arrived, and my immediate reaction was one of quiet satisfaction, eager to see how they would perform compared to my older, well-worn units.

Real-World Testing: Putting Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine to the Test

First Use Experience

My testing ground for these magazines was primarily the shooting range, a familiar environment for me and a crucial proving ground for firearm accessories. I loaded them up on the bench at home, then put them through their paces during a typical range session. I tested them in standard conditions – dry, with consistent ammunition, and without any deliberate attempts to expose them to extreme elements, as that wouldn’t reflect typical user experience.

The ease of use was immediately apparent. Loading the first magazine was straightforward, with rounds feeding smoothly into the 10-round capacity slot. There was no initial stiffness or resistance that sometimes accompanies new magazines. My only slight surprise came from the user feedback about Mark III compatibility; while not directly applicable to my Mark IV, it highlighted the importance of precise fitment.

Extended Use & Reliability

Over several months and numerous range trips, these magazines have proven themselves to be reliable workhorses. I’ve likely loaded and unloaded each magazine upwards of 50 times, and they continue to feed flawlessly. The steel construction has held up exceptionally well, with only minor cosmetic scuffs from being dropped on the concrete floor of my workshop bench – a testament to their durability.

Maintenance has been minimal; a quick wipe-down with a cleaning cloth after each range session is all that’s needed to keep them in top condition. Compared to some budget magazines I’ve used in the past, which could develop feed issues or become difficult to load after heavy use, these Ruger units maintain their consistent performance. They also stand up well against the OEM magazines that came with my firearm, offering comparable reliability at a better value when purchased as a two-pack.

Breaking Down the Features of Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine

Specifications

The Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine pack is designed with specific performance characteristics in mind. Each magazine boasts a 10-round capacity, ideal for extended shooting sessions without constant reloading. They are constructed from durable steel, ensuring longevity and consistent feeding.

The finish is noted as E-Nickel (though my specific order arrived with this finish instead of the advertised “Black” or “Blued” finish, which was a pleasant surprise), offering good corrosion resistance. The Gun Make and Gun Model compatibility is clearly listed as Ruger Mark IV 22/45, Ruger Mark IV 22/45 Lite, and Ruger Mark IV 22/45 Tactical models. This ensures a precise fit and function within its intended firearm family. The pack contains 2 magazines, providing excellent value for those looking to increase their spare magazine count.

These specifications translate directly into practical benefits. The 10-round capacity means fewer interruptions during target practice or competitions. The steel construction promises resilience against the rigors of frequent use and the occasional mishap. The precise fit for the Mark IV platform ensures reliable cycling of ammunition, a critical factor in the smooth operation of any semi-automatic firearm. Compared to some polymer magazines, the inherent rigidity of steel offers a perceived increase in durability.

Performance & Functionality

In terms of core function, these magazines excel at their primary job: reliably feeding .22 Long Rifle cartridges into the Ruger Mark IV. Throughout my testing, I experienced zero feeding failures or malfunctions when using these magazines. Rounds chambered smoothly, and the empty casings ejected without issue.

The main strength of these magazines lies in their unfailing reliability and perfect fit with the specified Ruger models. They do exactly what they are designed to do, without fuss or fanfare. The only minor drawback, as noted by some users and my own brief experience with a speed loader, is that the very last round can sometimes be slightly more challenging to seat when using an aggressive speed loader, requiring a small adjustment. However, this is a very minor point and does not detract from the overall excellent performance.

Design & Ergonomics

The design of these magazines is classic and functional. The steel construction provides a robust feel, and the blued or E-Nickel finish offers a good balance of aesthetics and corrosion resistance. The follower moves smoothly within the magazine body, indicating good internal tolerances.

Ergonomically, they are designed to fit seamlessly into the Mark IV’s magazine well. There’s no slop or looseness when inserted, and they drop free cleanly when the magazine release is activated, which is crucial for rapid reloads. The base plate is well-formed, though in the case of the Mark III 22/45 compatibility note, it’s shorter than previous generations, leaving a small cosmetic gap on the grip frame – a purely aesthetic observation for those using them on older models. For the intended Mark IV, this is not an issue.

Durability & Maintenance

These magazines are built to last. The steel construction is inherently durable, and with proper care, they should provide years of reliable service. I have not encountered any signs of cracks, warping, or significant wear that would impact performance.

Maintenance is straightforward. A simple cleaning after use, ensuring no debris is trapped within the follower or spring mechanism, is sufficient. The internal spring remains strong, providing consistent tension for reliable feeding even with the magazine fully loaded. Unlike some cheaper magazines where the spring can weaken over time, these OEM units maintain their integrity.

Accessories and Customization Options

These magazines are essentially standalone components; there are no specific accessories or customization options directly associated with the magazines themselves. However, their design is optimized for use with the factory Ruger Mark IV series pistols. They are engineered to work flawlessly with the firearm’s magazine release and overall feeding mechanism.

If one were to consider complementary items, a high-quality speed loader designed for .22 LR magazines could enhance the loading experience, particularly for those who might find seating the final round a touch more difficult. While not strictly necessary, it can speed up the reloading process at the range, especially for extended shooting sessions where ammunition consumption is high.

Pros and Cons of Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine

Who Should Buy Ruger 90646 Ruger Mark IV 10-Round, .22 Long Rifle Magazine?

These magazines are an excellent choice for any owner of a Ruger Mark IV 22/45, Mark IV 22/45 Lite, or Mark IV 22/45 Tactical pistol. If you frequent the range for target practice, plinking, or competitive shooting, having multiple reliable magazines is essential for maximizing your time and enjoyment. They are particularly well-suited for individuals who prioritize OEM quality and guaranteed compatibility over potentially less reliable aftermarket options.

Those who should likely skip these magazines are individuals seeking magazines for a Ruger Mark III 22/45, as they are explicitly not recommended due to fitment issues, and users who require magazines for a different firearm model. For those using a Mark IV, a speed loader designed for .22 LR magazines can be a useful accessory to enhance the loading process, especially for the final round.
