Hands-On with the Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine
As someone who’s spent over a decade putting gear through its paces in everything from dusty workshops to sterile labs and rugged outdoor environments, I approach new equipment with a healthy dose of skepticism and a keen eye for detail. The Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine arrived on my bench during a period of frustration with feeding issues in one of my .450 Bushmaster AR platforms. I’d been experiencing inconsistent cycling and feed failures, particularly with the last round, and was on the hunt for a more reliable solution than the often-temperamental polymer magazines or flimsy aftermarket followers available. My previous experience with Duramag products has generally been positive, leaning towards solid, no-nonsense manufacturing, so I was cautiously optimistic about this stainless steel offering. Initial impressions upon unboxing were of a robust, no-frills construction; it felt weighty and substantial, a stark contrast to some of the lighter polymer mags on the market. I’d briefly considered other brands, but Duramag‘s reputation for durable steel magazines, especially for higher-caliber AR platforms, ultimately steered my decision. There was a definite sense of relief mixed with anticipation as I prepared to integrate it into my existing setup.
Real-World Testing: Putting Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine to the Test
First Use Experience
My initial testing took place at my usual local range, a controlled environment where I could thoroughly cycle rounds and observe performance without external distractions. I tested the Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine with a variety of .450 Bushmaster ammunition, focusing on its ability to feed smoothly from a closed bolt and during rapid fire. The magazine was loaded to its stated 7-round capacity, and I meticulously observed the interaction between the bolt carrier group (BCG) and the top round during chambering. My specific upper was a BCA (Bear Creek Arsenal) with an Anderson lower receiver, a common configuration for .450 Bushmaster builds.
The first surprise was how well it performed right out of the box. Unlike some other magazines that require a break-in period, this Duramag fed rounds reliably without any initial hiccups. Cycling was noticeably smoother, and the issues I had experienced with the last round failing to feed completely vanished. Even when pushed to its full capacity, the magazine demonstrated a commendable ability to present rounds consistently to the BCG, which was a significant improvement.
Extended Use & Reliability
After several range sessions and countless magazine cycles, the Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine has proven itself to be a workhorse. I’ve used it in various conditions, including a moderately dusty outdoor range day and a couple of garage sessions where it was handled extensively while working on other projects. Its stainless steel construction and the Black T360 Coating finish seem to resist minor scuffs and dirt buildup quite effectively, requiring only a quick wipe-down to maintain.
Durability has been exceptional; there are no visible cracks, the polymer follower still moves freely, and the spring tension remains consistent. Compared to my prior experiences with polymer magazines for this caliber, which often develop feeding issues or spring fatigue over time, this steel magazine feels like it’s built for the long haul. Maintenance is straightforward – a simple field strip of the magazine, a quick clean with a brush and some solvent, and a light re-lubrication if necessary, is all that’s required. It’s a much less finicky affair than some more complex designs.
Breaking Down the Features of Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine
Specifications
The Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine boasts a set of specifications that highlight its robust design. Constructed from Stainless Steel, it’s engineered for durability and corrosion resistance, a critical factor for rifle magazines subjected to varied environments. The Black T360 Coating offers an additional layer of protection and a non-reflective finish, which is always a practical touch. Its 7 Round Capacity is specifically tailored for the .450 Bushmaster cartridge, a round known for its substantial dimensions.
Designed for the AR Platform, specifically the AR-15 rifle, this magazine aims for seamless integration. The inclusion of an Everflex Spring and a CPD Plate suggests a focus on reliable feeding and magazine longevity. While the exact dimensions aren’t provided, its capacity and caliber imply a slightly longer profile than standard 5.56 magazines to accommodate the larger .450 Bushmaster rounds. This attention to material and component quality is crucial for a component like a magazine, which is the direct interface for feeding ammunition into the firearm.
Performance & Functionality
In terms of core function – reliably feeding ammunition – the Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine performs admirably. Its primary job is to present rounds to the BCG without fail, and this is where it truly shines. The feeding has been consistently smooth, even when loading the full seven rounds. This is a significant upgrade from magazines that struggle with the last round, a common complaint with .450 Bushmaster setups.
The strengths lie in its robust construction and consistent feeding. The magazine appears to apply just the right amount of upward pressure to the rounds, allowing the BCG to strip them cleanly without excessive force. The main weakness, as noted by some users and confirmed in my own experience when attempting to seat a fully loaded magazine with the bolt closed, is that seven rounds can be a very tight fit. While it holds seven rounds, inserting it under pressure with a fully loaded mag can be challenging, often requiring more force than is ideal. This indicates that while the capacity is rated at seven, its practical application for immediate seating with a closed bolt might be better served at six rounds for optimal ergonomics.
Design & Ergonomics
The design of this Duramag magazine is undeniably functional and built for purpose. The Stainless Steel construction provides a tangible sense of solidity, and the Black T360 Coating offers a good grip without being overly abrasive. It feels substantial in hand, and the overall finish is uniform and professional.
Ergonomically, it fits well within standard AR-15 magwells. The follower is a standard polymer design that moves freely within the magazine body, contributing to smooth feeding. However, as mentioned, the challenge arises when trying to seat a full seven rounds with the bolt closed. The sheer pressure exerted by those seven rounds against the BCG, when the magazine is inserted, can make seating it difficult, sometimes even requiring considerable force. This isn’t a flaw in the magazine’s construction itself, but rather a limitation of fitting seven substantial .450 Bushmaster rounds into a package designed for the AR-15 platform without significant modification. Some users have suggested the magazine body could benefit from being a quarter-inch longer to alleviate this pressure, which would likely make seating a fully loaded seven-round magazine much easier.
Durability & Maintenance
The Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine is built for longevity, particularly for a component that undergoes significant stress. The use of Stainless Steel as the primary material inherently offers excellent resistance to rust and corrosion, making it a reliable choice for various climates and conditions. The Black T360 Coating further enhances this durability by providing a tough, abrasion-resistant surface.
Maintenance is relatively straightforward. Like any firearm magazine, it can benefit from occasional cleaning to remove debris that might impede the follower or spring. The steel construction means there are fewer concerns about cracking or fatigue that can plague polymer magazines over time, especially under the pressure of higher-caliber rounds like the .450 Bushmaster. Potential failure points would likely be related to the follower or spring over extreme usage, but given the quality of materials, this is less of a concern compared to lesser-quality alternatives. It’s a component designed to last, and my extended use has certainly supported this.
Accessories and Customization Options
The Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine comes with a few key components that contribute to its functionality. The Everflex Spring is designed for consistent tension over many cycles, ensuring that each round is reliably pushed upwards. The CPD Plate, likely referring to the base plate, is typically designed for ease of disassembly for cleaning and may offer a slightly improved grip or durability.
This particular model is not designed for extensive customization in the way some firearms or accessories are. Its purpose is singular: to reliably feed .450 Bushmaster rounds in an AR-15 platform. However, the core design and materials mean it integrates well into standard AR-15 setups. It doesn’t come with interchangeable parts or a wide array of optional add-ons, which aligns with its utilitarian design philosophy. Its strength lies in its core functionality rather than modularity.
