Description

6mm ARC AR-15 Carbon Fiber Barrels

Helix 6 Precision 6mm ARC carbon fiber AR-15 barrels are designed for precision shooters, hunters, competitors, and custom rifle builders seeking top-tier performance with easy installation. Each barrel is engineered with the appropriate gas system length for the cartridge and is precision chambered and headspaced for straightforward installation into a compatible AR-15 upper.

Built around a match-grade 416R stainless steel core, these barrels are button-rifled and hand-lapped, then wrapped using our proprietary high-carbon, low-resin carbon fiber process.

Unlike traditional carbon barrels, Helix 6 barrels are designed to maintain point of impact (POI) during extended strings of fire, providing consistent performance for precision shooting, hunting, and competition.

Each Helix 6 barrel carries a sub-½ MOA accuracy guarantee when used with match-grade ammunition, quality components, and by a capable shooter.
