The Cadex Defense Kraken Bartlein Replacement Barrel delivers elite-tier precision for extreme long-range shooter operations. Meticulously crafted by Bartlein Barrels, it utilizes single-point cut 5R match-grade rifling to optimize bullet stability while reducing copper fouling. The robust 20-inch heavy straight taper design provides incredible rigidity, minimal barrel whip, and superior thermal absorption. Engineered exclusively for the Cadex Kraken multi-caliber system, it integrates a proprietary breech torque system that allows operators to swap calibers in the field with a near-zero point-of-impact shift. Finished with a protective black coating, the muzzle features standardized 3/4"x24 TPI threading to cleanly support heavy-duty muzzle brakes or suppressors.
