GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension Review

Breaking Down My First Experience with the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension

For years, my Benelli M2 has been a reliable workhorse, but a nagging desire for increased capacity always lingered in the back of my mind. The standard configuration, while perfectly adequate for many tasks, often left me wishing for just a few more rounds on tap, especially during extended range sessions or when I was pushing the boundaries of its utility. This is precisely what led me to the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension. GG&G has a reputation for crafting robust, no-nonsense accessories, and this particular extension promised a straightforward way to enhance my shotgun’s firepower. I considered other brands, but GG&G’s reputation for using solid steel in critical components swayed my decision, as I’ve had issues with aluminum parts failing under stress in the past. My initial impression upon unboxing this magazine extension was one of solid craftsmanship; it felt substantial and well-machined, hinting at its intended purpose for demanding environments.

Real-World Testing: Putting GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension to the Test

First Use Experience

My initial testing for this magazine extension took place on the familiar concrete floor of my home workshop, where I meticulously disassembled and reassembled my Benelli M2. The installation process was remarkably smooth, requiring only basic field stripping knowledge of the shotgun. No specialized tools beyond what you’d expect for routine maintenance were needed, and the absence of any modification requirement to the shotgun itself was a significant plus. The extension threaded on cleanly, and the included spring fit perfectly.

After a successful initial installation, I took the M2 to my usual outdoor shooting range for a more rigorous evaluation. I ran a variety of 12-gauge loads through it, from light target loads to heavier buckshot, focusing on how the added weight and capacity affected cycling and perceived recoil. The extension performed flawlessly, with no hiccups in feeding or ejection, even when rapidly cycling through multiple shots.

The ease of use was immediately apparent; once installed, it simply became part of the shotgun, requiring no special handling beyond what one is accustomed to with a standard M2. The two extra rounds felt natural, and the overall balance of the shotgun remained surprisingly manageable. The only minor quirk I encountered was ensuring the internal magazine follower and spring were seated correctly to avoid any potential binding, which is more a point of careful installation than a flaw of the product itself.

Extended Use & Reliability

After several months of consistent use – which included a couple of dedicated range days, some drills on my property, and even a hunting trip where its increased capacity proved invaluable during some fast-moving waterfowl action – the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension has held up exceptionally well. I’ve deliberately exposed it to a light dusting of dirt and the occasional splash of rain without issue, and it continues to perform as if it were brand new.

Durability has been outstanding. There are absolutely no signs of wear and tear that would affect its function. The matte black finish remains intact, and more importantly, the internal components show no signs of stress or degradation. The steel components feel as robust as they did on day one, reassuring me that this isn’t a part that will fail when I need it most.

Maintenance has been straightforward. The ability to easily remove the end cap for cleaning is a thoughtful design choice that makes periodic maintenance a breeze. I simply give it a quick wipe-down with a solvent-soaked cloth and a light application of lubricant to the spring and follower. Compared to some aluminum extensions I’ve encountered that developed minute cracks or stripped threads after similar use, this steel-reinforced unit from GG&G feels like it’s built to last indefinitely.

Breaking Down the Features of GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension

Specifications

The GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension is engineered for compatibility with the 12-gauge Benelli M2 shotgun. It adds a 2-round capacity to the existing magazine, bringing the total capacity to six rounds when combined with the factory tube. The extension tube itself is machined from 6061-T6 aluminum, which is then Type III hard anodized in a non-reflective matte black finish, adhering to Mil-Spec standards for durability and low visibility.

Crucially, the magazine extension tube nut is CNC machined from wear-resistant solid steel bar stock, a significant advantage over competitors who might use aluminum here. This steel nut is manganese phosphated in a non-reflective combat finish, also per Mil-Spec. The unit measures 6.25 inches in length and weighs in at 6.8 oz. The package includes a new, extended length magazine spring specifically designed to ensure proper function with the added rounds.

These specifications translate directly into real-world performance. The use of 6061-T6 aluminum for the tube keeps the overall weight manageable, while the steel extension tube nut provides exceptional strength and resistance to wear, which is critical for retaining the barrel under recoil. The Mil-Spec finishes ensure that the component blends in with the shotgun and resists environmental damage. The inclusion of the extended spring is vital for reliable feeding of all rounds.

Performance & Functionality

In terms of its core function, adding capacity, the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension absolutely excels. It seamlessly integrates with the Benelli M2, allowing for two additional rounds to be loaded into the magazine tube. This increased capacity is a game-changer for anyone who needs more sustained firepower without frequent reloads.

The performance during cycling is where this extension truly shines. The solid steel ratchet base on the nut design ensures that the barrel is securely retained under recoil, preventing any unwanted shift or looseness. This translates to consistent reliability, even with a fully loaded magazine and during rapid firing sequences. I experienced zero feeding failures or malfunctions, which is a testament to GG&G’s engineering.

One significant strength is its robust construction, which directly impacts functionality. Unlike some lighter-weight extensions that might flex or loosen under stress, this unit feels incredibly solid. The primary drawback, if one can even call it that, is the slight increase in overall weight and length. However, this is an unavoidable trade-off for increased capacity and is handled exceptionally well by the product’s design.

Design & Ergonomics

The design of the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension is focused on function and durability. The 6061-T6 aluminum tube is precisely machined, offering a smooth surface that doesn’t interfere with shell feeding. The matte black, Type III hard anodized finish provides a professional, non-reflective appearance that complements the Benelli M2’s tactical aesthetic.

The magazine extension tube nut is a standout design feature. Its CNC machined steel construction and manganese phosphate finish speak to its intended use in demanding conditions. This component’s secure grip and robust build are essential for maintaining barrel integrity during firing. The nut also features a design that doesn’t protrude beyond the barrel on standard 18.5-inch models, maintaining a cleaner profile.

Ergonomically, the extension is virtually invisible once installed. It doesn’t create any new points of contact that would alter the shotgun’s feel or handling significantly. The ease of installation and the lack of any sharp edges or protruding parts contribute to a comfortable and intuitive user experience. The end cap can be removed separately, facilitating easier cleaning and the use of a magazine plug if required by local regulations.

Durability & Maintenance

Built with the understanding that these accessories can endure harsh conditions, the GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension is designed for long-term durability. The wear-resistant solid steel bar stock used for the extension nut is a key indicator of its longevity. Combined with the Mil-Spec finished aluminum tube, this unit is built to withstand significant use and abuse without degradation.

Maintenance is commendably simple. As mentioned, the removable end cap allows for easy access to the magazine spring and follower, facilitating regular cleaning and lubrication. This is crucial for ensuring consistent feeding and preventing malfunctions, especially after exposure to dust, grime, or moisture.

Potential failure points are minimal due to the robust materials and construction. The primary concern for any magazine extension is thread integrity, but the high-quality threading on both the shotgun’s receiver and the extension nut, coupled with the steel construction, makes stripping or cross-threading highly unlikely with proper installation. This extension is designed to be a permanent upgrade, not a disposable accessory.

Accessories and Customization Options

The GG&G Benelli M2 12ga 2-Shot Magazine Tube Extension comes as a complete kit for immediate installation. The primary accessory included is the new extended length magazine spring, which is essential for ensuring reliable function with the increased capacity. This spring is specifically calibrated to work with the added length and pressure of two extra shells.

While the extension tube itself isn’t a platform for further customization in the traditional sense (like adding rails or optics), its design allows for integration with standard Benelli M2 accessories. For example, the end cap’s design accommodates a magazine plug if needed for hunting regulations, making it adaptable to varying legal requirements. The non-reflective combat finish also ensures it pairs well with other tactical accessories on the market.

There are no other significant accessories included, nor are there typical customization options for the extension itself. Its purpose is singular: to reliably extend the magazine capacity. However, the quality of the included spring and the robust construction of the extension itself mean that no immediate aftermarket upgrades are necessary for optimal performance.
