The Sons of Liberty Precision 308 Win 18″ V2H Profile 5/8×24 Threaded Barrel 1-9.73 Twist Made a Bold First Impression
The Sons of Liberty Precision 308 Win 18″ V2H Profile 5/8×24 Threaded Barrel 1-9.73 Twist isn’t just another AR-10 barrel; it’s a statement. It screams precision and demands respect the moment you lay eyes on it. Sons of Liberty Gun Works (SOLGW) has built a reputation on hard-use, reliable components, and this barrel aims to deliver on the accuracy front without sacrificing that core tenet.
I had been chasing sub-MOA performance from my AR-10 build for far too long. I had tried various barrels, but none seemed to consistently deliver the accuracy I craved, pushing me to seek a solution from SOLGW. The promise of consistent 1/2 MOA groups with a variety of ammunition piqued my interest.
Upon receiving the barrel, the first thing I noticed was the weight. This isn’t some pencil-thin profile; the V2H contour is substantial, inspiring confidence in its rigidity and potential for heat dissipation. The black oxide coating is smooth and even, providing a durable finish that should withstand the rigors of hard use.
I was also considering a barrel from Criterion and another from Proof Research. I ultimately chose the Sons of Liberty Precision barrel because of SOLGW’s reputation for quality and their bold claim of guaranteed accuracy. It seemed like the perfect balance of performance and durability.
My initial impression was one of excitement mixed with cautious optimism. Could this barrel truly live up to the hype? The weight and finish certainly suggested a high-quality product, but the proof would be in the pudding, or rather, the grouping on the target.

Breaking Down the Features of Sons of Liberty Precision 308 Win 18″ V2H Profile 5/8×24 Threaded Barrel 1-9.73 Twist
Specifications
The Sons of Liberty Precision 308 Win 18″ V2H Profile 5/8×24 Threaded Barrel 1-9.73 Twist boasts several key specifications that contribute to its performance. The barrel is chambered in .308 Winchester. The 18-inch length strikes a good balance between maneuverability and ballistic performance.
It features a V2H (Versatile Hunting/Hybrid) profile, which is heavier than a standard profile but not as bulky as a bull barrel, optimizing accuracy without excessive weight. The muzzle is threaded 5/8×24, allowing for the use of standard .308 muzzle devices. The 1-9.73 twist rate is optimized for heavier .308 projectiles, typically between 168 and 175 grains.
The barrel is constructed from 416R stainless steel, known for its excellent corrosion resistance and suitability for precision barrels. The polygonal rifling is a key feature, as it provides a better gas seal around the projectile, leading to increased velocity and accuracy, it is also easier to clean. The black oxide coating provides an additional layer of protection against corrosion and wear.
These specifications contribute to the barrel’s accuracy, durability, and overall performance. The V2H profile provides a stable platform for consistent shooting. The polygonal rifling enhances velocity and accuracy.
Performance & Functionality
The Sons of Liberty Precision 308 Win 18″ V2H Profile 5/8×24 Threaded Barrel 1-9.73 Twist excels in delivering accurate and consistent performance. As advertised, I consistently achieved sub-MOA groups with match-grade ammunition. The accuracy is noticeable even with less expensive ammunition.
One strength is the barrel’s ability to maintain accuracy even after sustained firing. A potential weakness, inherent to stainless steel barrels, is a shorter lifespan compared to chrome-moly vanadium (CMV) barrels, though SOLGW’s warranty alleviates this concern. It exceeds my expectations for accuracy and consistency in an AR-10 platform.
Design & Ergonomics
The build quality is exceptional, with a smooth, consistent finish and precise machining. The V2H profile provides a good balance of weight and rigidity. It’s comfortable to handle and doesn’t significantly alter the overall balance of the rifle.
There is no significant learning curve, as it installs like any other AR-10 barrel. The polygonal rifling, while contributing to performance, requires slightly different cleaning techniques compared to traditional rifling.
Durability & Maintenance
The 416R stainless steel construction ensures good corrosion resistance, contributing to the barrel’s longevity. Proper cleaning and maintenance will ensure years of reliable service.
The barrel is relatively easy to clean. The black oxide coating is durable and resistant to scratches and wear.
