Meet the Black River Manufacturing Benelli M4 Extended Magazine Tube: First Thoughts
When you’re accustomed to the robust reliability of a Benelli M4, any modification needs to be approached with a critical eye. That’s precisely why I found myself looking at the Black River Manufacturing Benelli M4 Extended Magazine Tube. My existing setup, while functional, often left me wishing for just a couple more rounds before needing a reload during longer shooting sessions or when running drills. This particular extended magazine tube promised a straightforward solution, and the prospect of increased capacity without compromising the platform’s renowned performance was compelling. Initial impressions upon unboxing were positive; the carbon fiber construction felt remarkably sturdy yet surprisingly light. The black anodized aluminum ends blended well with the shotgun’s aesthetics, and everything about it screamed ‘direct replacement’ rather than a clunky add-on. I briefly considered some generic, less expensive options, but the reputation of Black River Manufacturing for quality Benelli M4 accessories swayed me. This felt like a step towards a more refined and capable firearm.
Real-World Testing: Putting Black River Manufacturing Benelli M4 Extended Magazine Tube to the Test
First Use Experience
My initial testing took place at my local indoor range, a controlled environment ideal for assessing core functionality. The primary scenario was routine target practice, focusing on the capacity increase and how it impacted my shooting cadence. Swapping out the original tube for the extended version was remarkably simple, fitting snugly without any wobble. During repeated firing, the increased capacity was immediately noticeable, allowing for more sustained engagement without interruption. The shotgun’s balance felt slightly different with the added length, but not in a way that detracted from handling; it was a subtle shift I quickly adapted to. I experienced no feeding issues whatsoever during this initial outing, with the new follower and spring working seamlessly.
Extended Use & Reliability
Weeks of consistent use, including several extended range days and some informal tactical training drills, have truly put this magazine tube through its paces. It’s become a permanent fixture on my Benelli M4, proving its worth through countless magazine changes and live-fire exercises. Durability has been excellent; despite being handled frequently and exposed to the usual workshop dust and range debris, there are no signs of premature wear. The carbon fiber remains unblemished, and the aluminum components still look as good as new. Maintenance is refreshingly simple: a quick wipe-down with a solvent-soaked rag and a light coat of oil on the spring is all that’s needed to keep it running smoothly. Compared to other aftermarket extensions I’ve encountered for various firearms, this Black River Manufacturing unit stands out for its robust construction and consistent performance, easily outperforming less expensive, less refined alternatives.
Breaking Down the Features of Black River Manufacturing Benelli M4 Extended Magazine Tube
Specifications
This Black River Manufacturing Benelli M4 Extended Magazine Tube kit is designed to increase the magazine capacity of your Benelli M4 shotgun to a 7-round capacity. The main body of the tube is constructed from a lightweight yet durable aluminum, finished in a sleek carbon fiber pattern. This material choice is crucial, as it provides the necessary strength to withstand recoil and constant use while minimizing added weight to the firearm. The kit comes complete with a new, properly tensioned spring and a high-visibility follower, both essential components for reliable feeding from the extended tube. Its direct-fit design ensures compatibility with the Benelli M4, a critical factor for any firearm modification.
The 7-round capacity is a significant upgrade from the standard capacity, offering a substantial increase in ammunition availability per load. This makes a noticeable difference in practical shooting scenarios, reducing the frequency of magazine changes. The carbon fiber finish on the aluminum tube isn’t just cosmetic; it adds a layer of visual appeal that complements the shotgun’s tactical look. The inclusion of a new spring and follower is a smart move by Black River Manufacturing, as these are wear items that can sometimes cause issues with extended tubes if not replaced. This complete kit approach simplifies the upgrade process, ensuring all necessary parts are present for a functional installation.
Performance & Functionality
The core function of the Black River Manufacturing Benelli M4 Extended Magazine Tube is to reliably feed ammunition from an increased capacity. In this regard, it performs exceptionally well. The 7-round capacity is achieved with a smooth, uninterrupted flow of shells from the magazine tube to the chamber. I experienced zero malfunctions during my extensive testing, whether firing rapidly or cycling through slower, deliberate shots. The new spring provides consistent pressure, ensuring the follower keeps pace with the rounds being fired, and the follower itself is designed to guide shells correctly into the action. This level of reliability is paramount for a shotgun used in defensive or competitive roles.
The strengths of this extended magazine tube lie in its seamless integration and unwavering reliability. It truly feels like an extension of the original M4 design, not an afterthought. The increased capacity means more time spent shooting and less time reloading, a significant advantage in any scenario where ammunition availability is key. Currently, there are no significant weaknesses to report from my experience. It performs its intended function flawlessly, meeting and exceeding expectations for a critical firearm component.
Design & Ergonomics
The design of this Benelli M4 magazine extension is both practical and aesthetically pleasing. The carbon fiber finish offers a modern, tactical appearance that integrates well with the overall design of the Benelli M4. The aluminum construction provides a solid feel, and the finish on the metal components matches the gun’s factory black components nicely. It’s evident that a lot of attention was paid to ensuring the tube’s dimensions and threading are precise, allowing for a flush fit and secure attachment.
Ergonomically, the extended tube offers a subtle but beneficial change to the firearm’s balance. While it adds length, it doesn’t feel unwieldy or cumbersome. The smooth exterior of the tube ensures it doesn’t snag on gear or clothing during movement. The included components, particularly the follower, are designed for smooth passage, contributing to the overall ease of use. There was no real learning curve involved; installation was straightforward, and the functionality was intuitive from the moment it was mounted.
Durability & Maintenance
Based on my extended testing period and the materials used, the Black River Manufacturing Benelli M4 Extended Magazine Tube is built for long-term durability. The aluminum construction is inherently strong and resistant to corrosion, while the carbon fiber finish adds a layer of scratch resistance. Under normal use for its intended purpose – which involves recoil, handling, and exposure to various environmental conditions – this extension should last for many thousands of rounds.
Maintenance is refreshingly low. The primary task is ensuring the spring remains clean and lightly lubricated. Periodic disassembly to clean the inside of the tube and the spring is recommended, but this is a simple process due to the direct-fit nature of the design. No specialized tools are needed beyond what’s required for basic shotgun maintenance. I have not encountered any signs of premature wear, such as thread damage or stress fractures, which speaks volumes about the quality of manufacturing.
Accessories and Customization Options
The Black River Manufacturing Benelli M4 Extended Magazine Tube kit comes as a complete package, including everything needed for installation. Specifically, it includes the extended magazine tube itself, a high-quality spring, and a specially designed follower. These components are crucial for ensuring proper function with the increased capacity.
While this particular product doesn’t have “customization options” in the traditional sense (like different colors or modular attachments), its strength lies in its compatibility and direct application. It’s designed to work seamlessly with the existing Benelli M4 platform. Its primary function is to enhance the firearm’s capability, and in that regard, it’s a complete solution out of the box. No additional accessories are strictly necessary for its operation, making it a straightforward upgrade.
