The Ballistic Advantage Modern 10.5-Inch .300 Blackout Barrel (brand part no. BABL300008M) is chambered in .300 AAC Blackout and machined from 4150 Chrome Moly Vanadium steel for strength under the pressure of both subsonic and supersonic .300 Blackout loads. It is finished with a QPQ corrosion-resistant coating, and the M4 feed ramp extension carries the same QPQ treatment for consistent feeding over the barrel’s service life. At 10.5 inches, it keeps a .300 Blackout AR pistol or SBR-length build compact while still giving the cartridge room to perform. It is part of Ballistic Advantage’s Modern Series, built as a working barrel rather than a boutique precision piece.
