Description

The Ballistic Advantage 20″ 22 ARC DMR Fluted Barrel is designed for superior precision, range, and thermal efficiency—crafted for demanding shooters who want to push their AR-15 platform to the limits of performance. Machined from 416R stainless steel and finished with aggressive spiral fluting, this barrel strikes the ideal balance between strength and weight savings, making it perfect for designated marksman rifle (DMR) builds.
With a rifle +1 length gas system for smooth cycling and reduced recoil, and a 1:7 twist rate optimized for heavy, high-BC 6mm bullets, this barrel is built to extract maximum performance from Hornady’s cutting-edge 22 ARC cartridge. The Nickel Boron-coated extended M4 feed ramp ensures reliable feeding under stress, while the bead-blasted finish gives it a clean, professional look.
