Heretic Labs Carbon Fiber Outer Barrel – 5.5″
The Heretic Labs Carbon Fiber Outer Barrel is a 5.5-inch genuine carbon fibre outer barrel for Wolverine MTW and Article HPA platform builds. Carbon fibre construction reduces weight compared to aluminium alternatives while maintaining the rigidity required for a precision HPA build, and the premium finish elevates the visual quality of the complete platform.
At 5.5 inches, this barrel suits CQB-configuration MTW builds where a short, lightweight outer barrel is a priority — providing the carbon fibre premium at a practical CQB length without the weight of longer alternatives. Heretic Labs designs its components specifically for the MTW and Article platform ecosystem, ensuring correct fit and compatibility throughout the build.
