The Ballistic Advantage Modern Series Barrel (brand part no. BABL300011M) is a 16-inch, .300 AAC Blackout barrel machined from chrome-moly-vanadium (CrMoV) steel and finished in QPQ for corrosion resistance. Ballistic Advantage cuts this barrel with a 1:7 twist rate and a pistol-length gas system, a combination that suits shorter-overall-length AR-15 builds and suppressed .300 Blackout setups that still want a full 16-inch barrel for a rifle configuration. It is a direct replacement or upgrade barrel for builders finishing out a .300 Blackout AR-15.
