XS Sight Systems Magazine +2 Extension and Detent Swage Tool Review

Unboxing & First Thoughts on the XS Sight Systems Magazine +2 Extension and Detent Swage Tool

The XS Sight Systems Magazine +2 Extension and Detent Swage Tool arrives as a deceptively simple kit, aiming to enhance the capacity of a venerable platform. For me, the need arose from a desire to squeeze a bit more utility out of a well-loved Remington 870 Express, specifically for scenarios where a few extra rounds could make a practical difference without a full tactical overhaul. My previous attempts to address the factory magazine tube dimples involved tedious hours with hand files, a process I wasn’t eager to repeat. This kit promised a more efficient solution, bundling the essential components needed for a +2 capacity upgrade.

Upon unboxing, the kit presents itself with a straightforward assembly. The extension tube, machined from 6061 aluminum and finished with a hard anodized coating, feels robust yet surprisingly lightweight. This immediately sets it apart from heavier, traditional steel extensions. The included Wolff spring appears to be of good quality, and the unique detent swage tool is what truly piqued my interest, appearing far more purpose-built than my DIY files. It’s a compact package that feels ready for immediate application, offering a tangible solution to a common shotgun owner’s mild annoyance.

While I did briefly consider simply purchasing a pre-assembled extended magazine tube, the inclusion of the detent swage tool tipped the scales in favor of this DIY kit. The ability to cleanly remove the internal obstructions myself, rather than relying on a potentially less effective or more damaging method, felt like a more controlled and cost-effective approach. My initial impression is one of practical innovation; it’s a kit designed for the end-user who values efficiency and a hands-on approach to firearm modification.

Real-World Testing: Putting XS Sight Systems Magazine +2 Extension and Detent Swage Tool to the Test

First Use Experience

My testing environment was my home workshop, a space familiar with modifications and repairs. The primary goal was to install the XS Sight Systems Magazine +2 Extension and Detent Swage Tool onto a Remington 870 Express. The process began with the detent removal. The provided detent swage tool proved remarkably effective; a few precise taps with a small hammer, as indicated by its design, cleanly pushed out the stubborn factory dimples without excessive force or risk of damaging the tube’s internal finish. This was a revelation compared to my previous filing endeavors, taking mere minutes instead of hours.

Following the detent removal, the installation of the extension tube and spring was straightforward. The 6061 aluminum tube threaded on smoothly, and the wrench flats on its tip allowed for a secure tightening. The 45″ Wolff 12 ga extended spring fit perfectly. Functionally, the first test was a simple manual cycling of rounds through the action. The added capacity was immediately evident, and the shotgun fed and ejected rounds without any hesitation. This initial trial in a controlled setting confirmed the kit’s immediate usability and effectiveness, bypassing the usual frustrations associated with similar modifications.

Extended Use & Reliability

Over several weeks, this +2 extension has seen regular use during range trips and dry-fire practice sessions. The 2-round capacity increase has been consistently reliable, allowing for an 8-round total on my 870 Express. I’ve cycled various types of 12-gauge ammunition through it, from light target loads to heavier buckshot, and the feeding mechanism has remained smooth and jam-free. The hard anodized finish on the aluminum tube has resisted minor scuffs and abrasions from handling, maintaining its appearance well.

Durability hasn’t been an issue so far. The extension tube feels solid and shows no signs of loosening or wear, even after being removed and reinstalled once for a thorough cleaning of the shotgun. Maintenance is as simple as cleaning the rest of the shotgun’s magazine tube; there are no special cleaning requirements for the extension itself. Compared to my previous experiences with less robust, generic magazine extensions, this XS Sight Systems offering feels significantly more integrated and reliable, avoiding the common pitfalls of inconsistent feeding or premature wear.

Breaking Down the Features of XS Sight Systems Magazine +2 Extension and Detent Swage Tool

Specifications

The XS Sight Systems Magazine +2 Extension and Detent Swage Tool kit is designed for the Remington Model 870 shotgun in 12 gauge. The core component is the plus two extension tube, meticulously machined from 6061 aluminum. This material choice contributes to a lightweight design, a significant advantage over traditional steel alternatives, with the extension weighing in minimally. The surface is protected by a hard coat anodized finish, providing excellent resistance to wear and corrosion, crucial for any firearm accessory.

The kit includes a 45″ Wolff 12 ga extended spring, specifically engineered to properly feed the increased number of rounds. The crucial element for easy installation is the custom-made detent tool, designed to precisely push out the factory detents in the Remington 870 magazine tube. This one-piece design extension tube measures 6 inches in length, ensuring it will not extend beyond the muzzle of most standard 4-round capacity shotguns, maintaining a balanced profile. It is designed to accept standard barrel clamps for added support and sling attachment options.

Performance & Functionality

The primary function of this kit is to increase the magazine capacity of a Remington 870 by two rounds, and it performs this task exceptionally well. The 2-round capacity increase is consistently delivered without any compromise in reliability. Ammunition feeds smoothly from the extended tube into the action, a testament to the quality of the included Wolff spring and the precise machining of the aluminum extension. The detent removal tool is a standout feature, making what was once a frustrating process incredibly simple and quick.

The strengths of this kit lie in its efficiency and effectiveness. The lightweight 6061 aluminum construction minimizes any added weight, which is a significant plus for shotgun handling. The integrated design and hard coat anodized finish contribute to a robust and durable performance. A minor point to consider is that while it works with the factory follower, some aftermarket followers might require minor fitting, though the product description notes compatibility with brands like Vang Comp, Nordic Components, and Wilson Combat. Overall, it exceeds expectations for a DIY upgrade kit, offering professional-grade results.

Design & Ergonomics

The design of the XS Sight Systems Magazine +2 Extension and Detent Swage Tool is focused on user-friendliness and practical functionality. The 6061 aluminum extension tube itself is a sleek, one-piece design, eliminating potential weak points found in multi-piece constructions. Its 6-inch length is well-proportioned, avoiding an overly extended look and ensuring compatibility with most barrel lengths without protruding past the muzzle.

The inclusion of wrench flats on the tip of the extension is a thoughtful ergonomic touch, allowing for a secure tightening without special tools. The hard coat anodized finish provides a non-slip, matte black surface that blends well with most shotgun finishes and feels good to the touch. The detent swage tool, while utilitarian in appearance, is ergonomically shaped for a comfortable grip during the installation process, making a potentially awkward task manageable.

Durability & Maintenance

This extension is built to last. The 6061 aluminum construction, combined with the hard coat anodized finish, suggests excellent resistance to wear and tear from typical shotgun use. The absence of any complex mechanisms or moving parts within the extension itself means there are fewer points of potential failure. Maintenance is straightforward; it simply requires being cleaned along with the rest of the shotgun’s internal components.

There are no specific maintenance quirks to worry about. Any potential concerns would likely stem from how aggressively the shotgun is handled or stored, but the robust materials and finish should withstand considerable abuse. The 45″ Wolff spring is also known for its durability and consistent tension over many cycles. Overall, the durability and low maintenance requirements make this a practical, long-term upgrade.

Accessories and Customization Options

The XS Sight Systems Magazine +2 Extension and Detent Swage Tool comes as a complete kit, with the primary “accessory” being the specialized detent swage tool. This tool is essential for the DIY installation, making it far easier than alternative methods. The kit also includes the 45″ Wolff 12 ga extended spring and the plus two extension tube itself.

While the extension tube is designed to accept standard barrel clamps, these are not included in the kit, but their compatibility is a valuable customization option. This allows users to add accessories like tactical lights or sling mounts, further enhancing the shotgun’s utility. The 6061 aluminum construction is also noted to work well with aftermarket followers, offering another avenue for customization if desired.
