Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 Review

The Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 in Action: First Look

For years, my Remington 870 platform has been a workhorse, a reliable tool that has seen its fair share of use. However, the fixed stock configuration, while dependable, limited its adaptability, particularly when paired with modern optics. The desire for a more modular and adaptable shotgun, especially for tactical applications and range days where quick target acquisition is key, led me to seek a solution. After much deliberation, I settled on the Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870. This upgrade promised to transform the classic 870 into a more modern, adjustable firearm, bridging the gap between traditional pump-action reliability and contemporary accessory integration. My initial impression upon unboxing this kit was one of robust construction and thoughtful engineering. Compared to some of the more crude aftermarket solutions I’d encountered for other platforms, this kit felt substantial and well-finished. It was with a sense of anticipation and relief that I began the installation process, eager to see if it would live up to its promise.

Real-World Testing: Putting Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 to the Test

First Use Experience

My initial testing of the Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 took place on a familiar shooting range, a place where I’ve wrung out countless pieces of gear. The installation itself was straightforward, requiring only basic tools and about thirty minutes of focused work. The real test came on the firing line; the adapter immediately improved the platform’s handling, allowing for a much more natural cheek weld when shouldering the firearm. I tested it with various loads, from light birdshot to heavier buckshot, observing how the adjustable stock and the added mass of the adapter affected felt recoil. The ergonomics were a significant improvement over the factory fixed stock, offering a more customizable length of pull which was invaluable for different shooting stances. No immediate issues or quirks presented themselves; the fit was precise, and everything functioned as expected right out of the gate.

Extended Use & Reliability

After several months of regular use, including numerous range trips and some static training drills, this adapter has proven its mettle. It’s become a permanent fixture on my Remington 870, a testament to its effectiveness and durability. I’ve exposed it to varying weather conditions, from humid summer days to crisp autumn mornings, and it has shown no signs of degradation. The powdercoat finish remains robust, resisting minor scuffs and scrapes encountered during transport and handling. Maintenance has been minimal; a quick wipe-down with a silicone cloth is usually all that’s needed to keep it looking and performing its best. Compared to other stock adapter systems I’ve used on different shotgun platforms, this Mesa Tactical offering stands out for its solid integration and the sheer modularity it brings to the classic 870 design. It truly elevates the shotgun’s capabilities without compromising its inherent reliability.

Breaking Down the Features of Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870

Specifications

The Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 is constructed from investment cast aircraft grade aluminum, which is then CNC machined for precision and durability. The entire assembly is finished with a tough, chemical resistant powdercoat in black, ensuring it can withstand rigorous use in various environments. A key specification is the high-tube design, which specifically elevates the comb to achieve optimal eye alignment with optics mounted on the included Picatinny rail. This rail, which can be either nine or twenty-four inches in length depending on the kit configuration, provides ample space for mounting a variety of aiming devices. The adapter itself is designed to accept standard AR-15 buffer tubes and collapsible stocks, dramatically increasing the customization options for the Remington 870 platform. This specification is critical, as it opens the door to a vast aftermarket of stocks and pistol grips.

• Material: Investment Cast Aircraft Grade Aluminum
• Finish: Tough, Chemical Resistant Powdercoat (Black)
• Design: High-tube for optimal optic alignment
• Rail Type: Picatinny (included, available in 9″ or 24″ lengths)
• Compatibility: Accepts standard AR-15 buffer tubes and collapsible stocks
• Shotgun Platforms: Remington 870 (also available for Mossberg 500/590)
• Installation: No gunsmithing required, minor fitting of fasteners may be necessary.

Performance & Functionality

The primary function of the High-tube adapter is to facilitate proper cheek weld and eye alignment with optics, and in this regard, it excels. The elevated comb is precisely what’s needed when running an optic like an ACOG or an LPVO that sits higher than traditional iron sights. This allows for a much more natural and stable shooting position, leading to quicker follow-up shots and improved accuracy. The included Picatinny rail is a solid platform for mounting various optics, and its construction feels robust enough to handle the recoil of a 12-gauge shotgun. The ability to attach an adjustable AR-15 style stock means the length of pull can be precisely tuned for individual shooters or different shooting conditions, a significant advantage over fixed stocks. The addition of a hydraulic buffer (sold separately or included in some kits) further enhances performance by reducing felt recoil, making the platform more manageable during extended shooting sessions.

Design & Ergonomics

The design of the Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 is fundamentally about bringing AR-15 modularity to a pump-action shotgun. The adapter itself is a stout piece of machinery, with clean lines and a purposeful aesthetic. The powdercoated finish offers a good grip and resists fingerprints and smudges, which is a practical consideration for any tool that gets handled frequently. The integration of the Picatinny rail directly into the adapter’s design is seamless, providing a stable and integrated aiming solution. Ergonomically, the real win comes from the ability to pair it with an AR-15 pistol grip and collapsible stock. This allows for a much more comfortable and customizable grip than the traditional shotgun grip, and the adjustable stock means you can dial in the perfect length of pull for your body type and shooting style. The high-tube aspect, while requiring an optic, is the key to achieving proper alignment.

Durability & Maintenance

Durability is clearly a strong suit of this adapter kit. The use of investment cast aircraft grade aluminum and a tough, chemical resistant powdercoat means it’s built to endure the rigors of tactical use, range days, and even more demanding applications. I’ve yet to see any significant wear, such as cracks, deep gouges, or loss of finish, despite using it regularly. The adapter is essentially a solid block of metal designed to replace the fixed stock’s mounting point, and its robust construction suggests it will last for the lifetime of the shotgun. Maintenance is incredibly simple: a quick wipe-down with a cloth is sufficient. There are no complex mechanisms to clean or lubricate. The few fasteners included are standard, high-quality hardware that are easy to replace if ever needed.

Accessories and Customization Options

The Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870 comes as a complete kit, or at least the adapter kit contains the essential components for the upgrade. The kit includes the cast aluminum stock adapter, a receiver cap screw, receiver screw hex key, an AR grip screw, and the Picatinny scope rail with its associated screws and hex key. It also comes with machined nylon spacers and aluminum mount point cover plates with their specific screws and hex key. Furthermore, two threaded steel flush cups are included for sling attachment points. While a complete stock kit would include an AR-15 buttstock and pistol grip, this adapter kit allows users to choose their preferred AR-15 compatible stocks and grips, offering a vast spectrum of customization. The option to purchase a Crosshair™ hydraulic recoil buffer separately, or as part of a complete kit, is another significant accessory that enhances functionality.

Pros and Cons of Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870

Who Should Buy Mesa Tactical High-tube Telescoping Stock Adapter and Rail Kit for Rem 870?

This adapter kit is an absolute game-changer for anyone looking to modernize their Remington 870 for tactical applications, competition shooting, or even home defense. It’s ideal for shooters who want to run red dots, holographic sights, or low-power variable optics (LPVOs) on their pump-action shotgun. If you appreciate the adjustability and ergonomics of AR-15 platforms and wish to bring that functionality to your scattergun, this kit is a must-have. It’s perfect for law enforcement officers, competitive 3-gun shooters, or even dedicated enthusiasts who want to maximize their shotgun’s adaptability.

Those who prefer traditional iron sights and have no intention of using an optic might want to look at other Mesa Tactical adapter options, like their LEO line, which sits lower and doesn’t require a rail. Additionally, if you are looking for a simple, no-frills shotgun without the desire for advanced accessory mounting, this kit might be overkill. For those considering this upgrade, I highly recommend pairing it with a quality AR-15 collapsible stock and a Hogue rubber overmolded pistol grip for the best ergonomic experience. A Crosshair™ hydraulic buffer is also a worthwhile addition for managing recoil, especially with heavier loads.
