Full description and what we offer
Carbon Six builds replacement rifle barrels designed around two priorities: weight and accuracy. They use McGowen Precision Rifle Barrel blanks as their foundation, chambering them in everything from .17 to .458 caliber.
With proper load development, CarbonSix barrels will easily shoot 1/2 MOA. While we cannot control the shooter, these barrels are extremely accurate.
The math is straightforward: a quality blank matters, but the gunsmith and your ammunition setup matter equally. Carbon Six will provide recommendations on twist rates, but they direct customers to bullet manufacturers like Berger (who offer a twist rate calculator) for load-specific guidance.
You pick the specs. They build it.
- •.22 (6 twist rate options: 1:6" through 1:16")
- •.270 Winchester, 277 Furry, 6.8 Western, 270 WSM, 27 Nosler

- •6.5mm (6.5 Creedmoor, 6.5 PRC, 260 Remington, 26 Nosler)
