Phase 5 Weapon Systems Inc Hexone AR15 Rifle Buffer Tube, /Complete Assembly Review

Let’s Dive into Phase 5 Weapon Systems Inc Hexone AR15 Rifle Buffer Tube, /Complete Assembly

The Phase 5 Weapon Systems Inc Hexone AR15 Rifle Buffer Tube, /Complete Assembly is a unique component designed to add a distinct aesthetic and potentially enhanced durability to your AR-15 rifle platform. Manufactured by Phase 5 Weapon Systems Inc, this buffer tube features a hexagonal design crafted from 7075-T7 aluminum. Its robust construction and eye-catching appearance make it stand out from standard mil-spec buffer tubes.

I was looking to add a unique touch to a rifle build that I was planning. Standard mil-spec components are reliable, but I wanted something with a bit more visual flair and that could potentially offer increased rigidity.

My first impression upon unboxing the Hexone was that it’s a substantial piece of hardware. The hexagonal shape is immediately striking, and the finish is smooth and clean. The weight feels appropriate for a rifle buffer tube made from quality aluminum.

Compared to standard mil-spec buffer tubes and even some enhanced cylindrical options from brands like BCM or Vltor, the Phase 5 Hexone is distinctly different. I chose the Hexone over those for its unique design and potential for increased strength, sacrificing compatibility with traditional stocks for its visual and structural appeal. I was excited to see it installed on my rifle.

Real-World Testing: Putting Phase 5 Weapon Systems Inc Hexone AR15 Rifle Buffer Tube, /Complete Assembly to the Test

First Use Experience

I tested the Phase 5 Hexone on a newly built AR-15 rifle at my local outdoor shooting range. The rifle was chambered in 5.56 NATO and equipped with a standard rifle-length gas system. Initial testing involved a series of drills at distances ranging from 25 to 100 yards.

The weather conditions were dry and sunny, with a slight breeze. The Hexone performed as expected in terms of its primary function as a buffer tube, adequately housing the buffer and spring assembly. However, the hexagonal shape proved incompatible with a Magpul PRS stock I initially intended to use.

Despite the initial stock incompatibility hiccup, installation of the included castle nut and endplate was straightforward, requiring no specialized tools beyond a standard AR-15 wrench. There were no immediate issues or malfunctions noted after the first use, apart from realizing it would require a compatible stock.

Extended Use & Reliability

After several months of use, involving approximately 500 rounds fired through the rifle, the Phase 5 Hexone has held up remarkably well. There are no signs of wear or tear on the finish, even after being subjected to some light bumps and scrapes. Regular cleaning involves simply wiping down the exterior with a CLP-soaked cloth, and I’ve observed no corrosion or discoloration.

The Hexone has proven to be exceptionally durable. Its thick walls and robust construction instill confidence. Compared to my previous experiences with standard mil-spec buffer tubes, the Hexone seems noticeably more rigid and resistant to bending or damage.

Breaking Down the Features of Phase 5 Weapon Systems Inc Hexone AR15 Rifle Buffer Tube, /Complete Assembly

Specifications

• Material: The Phase 5 Hexone is crafted from USA-sourced 7075-T7 aluminum, a high-strength alloy known for its excellent durability and resistance to corrosion. The use of 7075-T7 ensures that the buffer tube can withstand the stresses of repeated firing cycles and harsh environmental conditions.
• Design: Its hexagonal design is not just for aesthetics; it provides a thicker and arguably stronger structure compared to traditional cylindrical buffer tubes. The hexagonal shape allows for greater material thickness without significantly increasing weight.
• Dimensions: Edge to Edge OD is 1.4 inches, and Flat to Flat OD is 1.25 inches. These dimensions are critical for understanding stock compatibility and overall fit within an AR-15 rifle system.
• Compatibility: It fits Mil-Spec and billet lower receivers. This ensures broad compatibility across different AR-15 platforms.
• Included Components: The complete assembly includes the Hexone rifle length buffer tube, castle nut, and endplate. These components are essential for installation and ensuring a secure fit.
• Finish: The rugged tumbling process strengthens the exterior and leaves a smooth, snag-free surface. This enhances both the aesthetic appeal and the functional performance of the buffer tube.

Performance & Functionality

The Phase 5 Hexone functions as a standard rifle-length buffer tube, providing a housing for the buffer and spring assembly. Its primary function is to facilitate the cycling of the AR-15’s action, ensuring reliable feeding, extraction, and ejection of cartridges. The Hexone excels in this role, providing a smooth and consistent cycling action.

The hexagonal design is a visual upgrade that offers a stiffer buffer tube. However, the main weakness is stock compatibility – it requires stocks specifically designed for its unique shape. It meets expectations as a durable and functional rifle buffer tube, though only when paired with the correct stock.

Design & Ergonomics

The Phase 5 Hexone is CNC-machined from a single piece of 7075-T7 billet aluminum, showcasing exceptional build quality. The hexagonal shape provides a unique aesthetic and is surprisingly comfortable to handle. Installation is straightforward, and the included castle nut and endplate fit securely.

The Hexone is not user-friendly in the sense of universal compatibility. Its unique shape necessitates using a specific stock designed to fit it. The hexagonal design may require some visual adjustment for those accustomed to traditional AR-15 buffer tube shapes.

Durability & Maintenance

Constructed from high-strength 7075-T7 aluminum and finished with a rugged tumbling process, the Phase 5 Hexone is built to last. Regular cleaning and maintenance involve simply wiping down the exterior with a CLP-soaked cloth. The durable finish resists scratches and corrosion.

There are no special maintenance or repair requirements for the Phase 5 Hexone. Its robust construction ensures that it can withstand the rigors of regular use and harsh environmental conditions.

Accessories and Customization Options

The Phase 5 Hexone comes as a complete assembly, including the buffer tube, castle nut, and endplate. It is designed to be compatible with the Phase 5 Micro Stock.

The Hexone is compatible with most AR-15 lower receivers. However, it is crucially important to note that its unique hexagonal shape limits stock options to those specifically designed for it.
