The Sons Of Liberty Gun Works Combat V2 Profile 5.56x45mm NATO 14.50″ Threaded, Mid-Length Gas System Made a Bold First Impression
After a decade spent building and customizing AR-15 platforms for everything from competitive shooting to serious tactical applications, I thought I’d seen it all. Then I got my hands on the Sons Of Liberty Gun Works Combat V2 Profile 5.56x45mm NATO 14.50″ Threaded, Mid-Length Gas System, and my assumptions were challenged. This isn’t just another barrel; it’s a meticulously engineered component designed to address the real-world challenges faced by modern AR users.
I was seeking a barrel that could mitigate point-of-impact shift when transitioning between suppressed and unsuppressed configurations, a problem I’d encountered far too often during training exercises. My initial unboxing revealed a barrel with a distinct profile, clearly demonstrating that Sons Of Liberty Gun Works had prioritized intelligent weight distribution. The QPQ finish looked immaculate, promising enhanced corrosion resistance.
Compared to barrels from Faxon Firearms and Ballistic Advantage that I’ve used previously, the SOLGW Combat V2 felt more robust, with a deliberate focus on rigidity behind the chamber. I chose this barrel specifically for its advertised reduction in POI shift and optimized gas system, hoping to finally solve a persistent issue. My first impression was excitement tempered by a healthy dose of skepticism, eager to see if the claims held up under fire.
Real-World Testing: Putting Sons Of Liberty Gun Works Combat V2 Profile 5.56x45mm NATO 14.50″ Threaded, Mid-Length Gas System to the Test
First Use Experience
My first range trip with the SOLGW Combat V2 was at a local outdoor range, where I subjected it to a series of tests using both suppressed and unsuppressed configurations. The weather was typical for late spring: a mix of sunshine and sporadic light rain. I focused on evaluating accuracy at 50 and 100 yards with various ammunition types, including 55-grain FMJ, 62-grain green tips, and 77-grain match ammo.
The barrel settled in quickly, and I noticed a significant improvement in consistency compared to some of my previous builds. There was a slight break-in period of approximately 50-100 rounds. The mid-length gas system proved smooth and reliable, cycling flawlessly with all ammo types tested, even when suppressed.
The immediate benefit was noticeable: reduced POI shift when swapping between suppressed and unsuppressed. After the first use, I experienced some challenges aligning the gas block. However, that subsided after making adjustments and tightening all screws to the appropriate specs.
Extended Use & Reliability
After several months of regular use, including weekly range sessions and a carbine course, the SOLGW Combat V2 has proven to be exceptionally durable. I haven’t observed any significant wear or degradation of the QPQ finish, even after repeated cleaning and exposure to various solvents. The bore remains pristine, and accuracy hasn’t diminished.
Maintenance has been straightforward, requiring only standard cleaning procedures after each range visit. Compared to other barrels I’ve used, this one seems to resist fouling better, likely due to the high-quality finish and precise bore dimensions. It has dramatically outperformed my previous barrel experiences. It offers significantly better consistency and less sensitivity to ammunition variations.

The SOLGW Combat V2 excels in both accuracy and reliability. With quality ammunition, I consistently achieved sub-MOA groups at 100 yards, demonstrating the barrel’s inherent precision. The optimized gas port size ensures reliable cycling with a wide range of ammunition and suppressors, avoiding over-gassing or short-stroking issues.
The barrel’s primary strength lies in its ability to maintain consistent accuracy across different shooting conditions and configurations. A minor weakness is the limitation on fixed front sight bases, requiring the use of a low-profile gas block. Overall, the barrel exceeds expectations, delivering consistent performance that instills confidence in its dependability.
