Helix 6 Precision, Carbon Fibre Blank, 26.0" Length, 1.18" Diameter, 6mm Cal, 1-8 Twist

Helix 6 Precision, Carbon Fibre Blank

Helix 6 Precision’s carbon fiber barrel blanks are built for custom rifle builders, precision shooters, and backcountry hunters who demand uncompromising performance. Each blank features a hand-lapped, match-grade 416R stainless steel core, button-rifled for exceptional consistency. Wrapped with our proprietary high-carbon, low-resin composite, these barrels offer ultra-lightweight strength and accuracy — with virtually no point of impact (POI) shift, even under heat.

FEATURES

• Cut-to-Length Design – Steel core is large enough for 5/8-24 muzzle threading at any length. Blanks can be finished at the listed length (27") or cut shorter. Each inch removed reduces weight by ~1.5 oz.

• High Carbon, Low Resin Ratio – Superior thermal stability and performance.

• Hand Lead-Lapped – Delivers a consistent bore diameter and smooth finish.

• Minimal POI Shift – Maintains zero during extended strings of fire thanks to our proprietary carbon wrapping process.
