First Impressions of Haley Strategic Partners Thorntail X M-LOK Inline Light Mount
In the world of tactical accessories, optimizing weapon configuration is paramount, and the Haley Strategic Partners Thorntail X M-LOK Inline Light Mount aims to do just that. From Haley Strategic Partners, this mount promises to provide versatile light placement options while maintaining a low profile. I was drawn to this product seeking a streamlined solution to mount a weapon light without adding unnecessary bulk to my AR-15 platform.
For years, I’ve struggled to find a light mounting solution that strikes the perfect balance between functionality and ergonomics. Many mounts either protrude excessively or limit the positioning of the light, hindering natural thumb-over-bore techniques. Upon unboxing, the Thorntail X M-LOK Inline Light Mount exuded a sense of robust quality, with its clean lines and matte black finish.
Compared to the Magpul M-LOK Offset Light Mount and the Arisaka Inline Scout Mount, the Haley Strategic Partners option seemed to offer a slightly more compact design with a greater range of adjustability. I chose the Thorntail X primarily for its seven potential light positions and the reputation of Haley Strategic Partners for producing durable, combat-proven gear. My initial excitement stemmed from the promise of a truly customizable and unobtrusive light mounting solution, something I felt had been lacking in my previous setups.
Real-World Testing: Putting Haley Strategic Partners Thorntail X M-LOK Inline Light Mount to the Test
First Use Experience
I first tested the Haley Strategic Partners Thorntail X M-LOK Inline Light Mount during a night shoot at a local outdoor range. The conditions were mildly dusty, but otherwise clear. Installation was straightforward, and I quickly found a comfortable light position that allowed for easy activation with my support-hand thumb while maintaining a solid grip.
However, I immediately ran into issues when attempting to mount my Streamlight ProTac HL-X. Despite the product description including the ProTac HL-X, the light body was too long, preventing proper tightening of both M-LOK screws. I had to use only a single screw, which made me worry about the mount’s long-term stability.
Extended Use & Reliability
After several range sessions and a weekend-long training course, the Thorntail X has shown some resilience, although my initial concerns about the single-screw mounting proved warranted. While the mount itself hasn’t failed, the light shifts slightly under heavy recoil. Cleaning and maintenance are simple, requiring only a quick wipe-down after each use.
Compared to my previous experience with a Picatinny rail-mounted light, the Thorntail X offers a much lower profile, improving overall ergonomics. However, the issue with light compatibility remains a significant drawback. The mount, as advertised, should have worked with the Streamlight ProTac HL-X, but it unfortunately did not.
Breaking Down the Features of Haley Strategic Partners Thorntail X M-LOK Inline Light Mount
Specifications
The Haley Strategic Partners Thorntail X M-LOK Inline Light Mount is designed to directly attach a weapon light to an M-LOK rail system. It’s machined from 7075-T6 Aluminum, offering nearly twice the tensile strength of mounts made from the more common 6061-T6 Aluminum. This mount features a MIL-A-8625 Type III hard coat anodized finish for enhanced durability and corrosion resistance.
The mount is designed to provide seven different light positioning options around the rail, allowing for optimal placement based on user preference and handguard configuration. It’s compatible with a range of popular weapon lights, including Surefire M600 series, Cloud Defensive REIN series, Modlite OKW/PLH, Arisaka 300/600/18650 series, and Olight Odin. The mount weighs approximately 1.2 ounces, maintaining a lightweight profile.
Performance & Functionality
When mounted correctly (with compatible lights), the Thorntail X M-LOK Inline Light Mount performs admirably, offering a secure and streamlined platform. Its strength and rigidity contribute to maintaining zero under recoil. Unfortunately, the misleading product description regarding Streamlight compatibility is a major functional drawback.
The adjustability is excellent, allowing users to fine-tune light placement for optimal ergonomics. However, the light compatibility issue significantly diminishes its value. The Thorntail X meets the expectation of a low-profile and customizable light mount, but falls short on its advertised compatibility.
Design & Ergonomics
The Thorntail X is designed with a sleek, minimalist aesthetic. Its low-profile design contributes to improved weapon handling. The build quality is excellent, with the 7075-T6 aluminum providing a robust feel.
The mount is generally user-friendly, but the light compatibility issue adds an unnecessary layer of complexity. The provided hardware is high-quality, and the M-LOK interface is secure and reliable.
Durability & Maintenance
The 7075-T6 aluminum construction and hard coat anodized finish suggest excellent long-term durability. With proper care, the Thorntail X should withstand years of use in demanding conditions. Maintenance is straightforward, requiring only occasional cleaning.
Given its simple design and robust materials, the Thorntail X is unlikely to require frequent repairs. Its longevity is a significant selling point.
Accessories and Customization Options
The Haley Strategic Partners Thorntail X M-LOK Inline Light Mount itself doesn’t come with any additional accessories beyond the necessary mounting hardware. Its customization lies in its versatile light positioning options. Compatibility with various light brands makes it adaptable to different setups.
While the Thorntail X doesn’t directly support additional accessories, its M-LOK interface ensures compatibility with any M-LOK-compatible rail covers or hand stops. It integrates seamlessly with existing M-LOK platforms.
