Ballistic Advantage Premium Series Barrel Features The Ballistic Advantage Premium Series Barrel is machined from 416R stainless steel in a DMR profile balancing rigidity for accuracy with a weight that keeps the rifle manageable in the field. Chambered in 6mm ARC the barrel pairs with a 1:7 twist rate suited to stabilizing the longer heavier for caliber bullets favored by that cartridge for extended-range shooting. The 20 length and rifle-length gas system work together to extract full velocity from the 6mm ARC load while keeping the action s gas impulse smooth and consistent. A 5/8x24 threaded muzzle accepts standard muzzle devices giving the shooter flexibility to add a brake comp or suppressor mount. The bead blasted finish on this barrel gives it a uniform matte silver appearance that resists glare which helps keep the shooter s position concealed in the field. Premium Series barrels from Ballistic Advantage also feature a Nickel Boron coated extended M4 feed ramp extension improving feeding reliability as rounds move from the magazine into the chamber. Built to fit AR platform rifles this barrel gives precision shooters a durable accurate upgrade path for a 6mm ARC build.
