Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount Review

Meet the Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount: First Thoughts

The need for readily accessible spare ammunition is a constant consideration for any firearm owner, particularly those utilizing versatile platforms like the Mossberg 500/590 series. This is where the Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount enters the picture, aiming to solve that very problem. Monstrum has produced a dual-purpose accessory designed to keep spare shells within easy reach while also offering a rail for further customization. My own requirement for this type of accessory stemmed from a desire to optimize my Mossberg Shockwave for quick follow-up shots without fumbling for a separate pouch.

Initial impressions of this unit are positive. The construction feels robust, with a good weight that suggests durability. The design, a two-piece system that must be mounted together, immediately signals a robust integration rather than a flimsy add-on. I had considered other standalone shell carriers, but the integrated rail was a significant draw, promising added utility. My first reaction upon unboxing was one of quiet satisfaction, a feeling that a practical solution to a common problem had arrived.

Real-World Testing: Putting Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount to the Test

First Use Experience

My testing grounds were primarily at the local indoor range, where quick reloads and the ability to maintain a defensive posture are paramount. I mounted this shell carrier onto a Mossberg Shockwave 20-gauge, a platform where space is at a premium and every bit of accessory integration counts. The unit installed directly into the factory mounting holes, a point of significant ease that avoided any need for specialized tools or gunsmith intervention.

During a training session focusing on rapid firing drills, the shell carrier performed admirably. It held the seven 20-gauge shells securely, with no accidental dislodges even during vigorous movement. The addition of the Picatinny rail allowed me to attach a small red dot sight, which noticeably improved my ability to acquire targets faster. The ambidextrous design meant I could position it on the left side of the receiver without any issues, catering to my shooting style.

Extended Use & Reliability

After several weeks of consistent use, including range visits and dry-fire practice sessions at home, the Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount has proven its worth. The polymer shell holders show no signs of stretching or deformation, continuing to grip the shells firmly. Even after repeated stress during reloads, the mount itself remains solid, with no play or loosening from the receiver.

Durability has been impressive; it has survived being bumped against doorways and handled with gloves without any significant cosmetic damage. Maintenance is straightforward: a quick wipe down with a cloth is all that’s needed to keep it clean. Compared to the elastic shell loops on some chest rigs I’ve used, this integrated solution offers superior rigidity and faster access.

Breaking Down the Features of Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount

Specifications

The Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount is engineered to provide convenient shell storage for specific Mossberg shotguns. It features a capacity for seven 20-gauge shotgun shells, ensuring you have ample spares readily available. The mounting system attaches directly to the receiver’s factory mounting holes, requiring no gunsmithing for compatible models.

Its design is ambidextrous, allowing installation on either the left or right side of the receiver, a crucial feature for shooter preference. The integrated Picatinny rail offers a versatile platform for mounting accessories like lasers or lights, further enhancing the shotgun’s utility. The unit is constructed from durable materials, presenting a black finish that complements most firearm aesthetics.

• Capacity: Holds seven 20-gauge shotgun shells. This ample capacity means fewer immediate reloads are necessary during extended shooting sessions or tactical scenarios.
• Mounting Type: Attaches via factory receiver mounting holes. This ensures a secure fit without requiring modifications to the firearm itself for most compatible models.
• Rail Type: Features an integrated Picatinny rail. This allows for the addition of various accessories, significantly increasing the shotgun’s functionality.
• Compatibility: Designed for Mossberg 500 and 590 Series shotguns, including Shockwave, 535, 835, and 590a1 models. Compatibility with pre-1997 models may require different screw sizes.
• Design: Ambidextrous mounting capability caters to all shooters. The two-piece design is meant to be mounted as a single unit, with neither part functional independently.

Performance & Functionality

In its primary role, this shell carrier excels at keeping spare shells accessible. The elastic loops hold the shells with just the right amount of tension – firm enough to prevent accidental loss, yet yielding enough for a quick, positive grip during reloads. The Picatinny rail is solid and provides a stable platform for accessories.

The key strength here is the seamless integration into the shotgun’s platform. It feels like a factory-installed component, not an afterthought. A minor point for consideration is that the rail is rather short, limiting the types and number of accessories you can mount simultaneously. However, for a single accessory like a laser or a compact light, it’s perfectly adequate.

Design & Ergonomics

The Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount boasts a functional and utilitarian design. The polymer shell loops are robust and have a textured finish that aids in gripping the shells. The overall construction feels solid, with no loose parts or rattling.

Ergonomically, the placement of the shells and the rail is well-considered. It positions the spares within a natural reach during a reload, and the rail is positioned to avoid obstructing the shooter’s grip or sight picture. The ambidextrous nature of the mount is a significant ergonomic advantage, allowing users to adapt it to their specific needs without compromise.

Durability & Maintenance

Based on my experience, the durability of this shell carrier appears to be quite high. The polymer used for the shell holders is flexible yet resilient, showing no signs of cracking or wear even after repeated shell insertions and removals. The mounting hardware and the rail itself feel sturdy.

Maintenance is minimal, primarily involving keeping the unit clean from dust and debris, which can be achieved with a simple wipe-down. There are no complex mechanisms or sensitive parts that require special care. I have not encountered any obvious points of failure, and I anticipate this accessory will hold up well over extended periods of use.

Accessories and Customization Options

The standout accessory integrated into this unit is the Picatinny rail. This allows for the attachment of a variety of tactical accessories. For instance, adding a small green laser sight can significantly improve target acquisition speed, especially on a platform like the Shockwave where ergonomics can be challenging.

While the unit itself doesn’t come with additional accessories, its compatibility with standard Picatinny accessories is its main selling point for customization. It doesn’t directly accommodate other mounts, but the rail itself offers a good starting point for tailoring the shotgun.

Pros and Cons of Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount

Who Should Buy Monstrum Mossberg 20-Gauge Shell Carrier with Picatinny Rail Mount?

This shell carrier is an excellent choice for owners of compatible Mossberg 500 and 590 series shotguns, particularly those looking to enhance their firearm’s tactical or defensive capabilities. It’s ideal for users of the Mossberg Shockwave who want to maximize its utility and have spare rounds readily available. Range shooters who perform frequent reloads will find this accessory a significant improvement in efficiency.

Individuals with pre-1997 Mossberg shotguns should be aware that they might need to source different mounting screws. Those seeking an extensive accessory rail system might find the integrated rail somewhat limited; in such cases, a dedicated forend or stock with multiple rail sections might be a better fit. For those focused on quick access to ammunition and the addition of a single, crucial accessory, this unit is a strong contender.
