The Ballistic Advantage Premium Series 6mm ARC Barrel (brand part no. BABL6MM002PQ) is an 18-inch AR-15 barrel built with an SPR profile and a rifle-length gas system. Ballistic Advantage machines it from steel and finishes it in black QPQ for corrosion resistance, then adds a nickel boron coated, extended M4 feed ramp extension for smoother feeding. A low-profile gas block keeps the barrel’s silhouette slim under a free-float handguard. Built for the 6mm ARC cartridge, a round designed to extend an AR-15’s effective range well past 5.56, this Ballistic Advantage barrel is ready for a precision or long-range build.
