The Ballistic Advantage Classic Series Barrel (brand part no. BABL556009MC) is a 14.5-inch, 5.56 M4 carbine-length barrel machined from chrome-moly-vanadium (CrMoV) steel with a chrome-lined bore. Ballistic Advantage applies a QPQ finish over the CrMoV steel and adds a QPQ-coated M4 feed ramp extension, giving builders a durable, low-maintenance barrel for a carbine-length AR-15 build. The chrome lining extends bore life and simplifies cleaning compared to an uncoated barrel.
