Overview

The ODIN Works 18" 6mm ARC XL Rifle DMR Profile barrel is designed for precision shooting, with an 18-inch length that balances velocity and accuracy. Its 1:7 twist rate is optimal for stabilizing a range of bullet weights, making it suitable for various ammunition choices, while the rifle-length gas system ensures reliable cycling and reduced recoil. This barrel commonly appears in precision-oriented builds, particularly those focused on long-range performance and target shooting.
