The Ballistic Advantage Modern Series Barrel (brand part no. BABL300002F) is an 8.30-inch, .300 AAC Blackout pistol-length barrel machined from 4150 chrome moly vanadium steel with a QPQ corrosion-resistant finish, built for the AR-15 platform. Ballistic Advantage cuts this DRP-profile Hanson Series barrel with a 1:7-inch twist, a nickel boron coated M4 feed ramp extension, and a pinned low-profile gas block, and every barrel is HP and MPI tested. As a bare barrel, federal NFA rules apply to how it can be paired with a lower receiver: it is legal to install on a pistol-configuration lower or a registered SBR/machine gun lower, but not on a non-NFA rifle lower.
