Sons of Liberty Gun Works
The Sons of Liberty Gun Works Precision 6mm ARC barrel is a match-grade option for shooters building or upgrading a precision rifle in this emerging intermediate cartridge. This 14.5-inch barrel features the SPR (Special Purpose Rifle) contour, a moderately heavy profile that strikes a balance between weight and handling while providing the rigidity needed for consistent, accurate shooting. The 416R stainless steel construction with black oxide coating delivers corrosion resistance and durability, while the polygonal rifling and 1-7.5 inch twist rate are optimized to stabilize and shoot 6mm ARC ammunition reliably across multiple loads. The 5/8×24 threaded muzzle accepts standard suppressors and muzzle devices, giving you flexibility for your setup.
What sets the Precision series apart is SOLGW's commitment to accuracy from the factory. These barrels are engineered to consistently print tight groups—routinely achieving 1/2 MOA or better with various ammunition types. That level of precision out of the box means less guesswork and more confidence when you're dialing in a new rifle or validating a load. The trade-off is that the SPR contour adds weight compared to lighter profiles, and the superior accuracy potential comes with a shorter barrel lifespan than their 4150CMV offerings. That's a fair exchange if you're chasing performance rather than extreme longevity.
Keep in mind the Precision barrels will wear faster than chrome-moly alternatives, but SOLGW backs every barrel they ship with their warranty—even if you manage to shoot one out, they'll replace it at no cost. Whether you're building a dedicated 6mm ARC long-range gun, a competition rifle, or upgrading an existing platform, this barrel rewards good shooter fundamentals and quality ammunition with the accuracy you're after.
| Caliber | 6mm ARC |
| Barrel Length | 14.5 inches |
| Contour | SPR (Special Purpose Rifle) |
| Material | 416R Stainless Steel |
| Finish | Black Oxide |
| Rifling | Polygonal |
| Twist Rate | 1-7.5 inch |
| Muzzle Thread | 5/8×24 |
SOLGW's Precision series is engineered for sub-MOA groups. Testing shows these barrels routinely deliver 1/2 MOA accuracy across multiple ammunition types, making them a solid choice for precision rifle builds and long-range shooting.
Yes. The 5/8×24 threaded muzzle is the standard for suppressors and muzzle devices in the rifle community, so you'll have no trouble finding compatible cans and brake options.
The Precision series has a shorter lifespan than SOLGW's 4150CMV barrels due to the stainless steel construction and match-grade optimization. However, SOLGW still warranty all Precision barrels, including free replacement if you shoot one out.
The SPR profile is moderately heavy—it's designed to provide the rigidity and heat capacity needed for precision shooting rather than minimal weight. If you're building a lightweight rifle, a lighter contour might suit your needs better.
