The Ballistic Advantage .300 Blackout 14.5-Inch Modern Series Barrel (brand part no. BABL300009M) is a Modern Series barrel from Ballistic Advantage chambered in .300 AAC Blackout, machined to a 14.5-inch length. It’s built from 4150 Chrome Moly Vanadium steel with a QPQ corrosion-resistant finish, giving it the corrosion resistance and durability to handle sustained range use. Because it’s shorter than the 16-inch federal minimum for a rifle barrel, it’s sold as an ordinary Title I part; the legal restriction is on how you assemble it, not on buying the barrel itself. It ships as a bare barrel, so plan on pairing it with your own barrel nut, gas system, and handguard.

Frequently Asked Questions

What’s included with this barrel? It ships as a bare barrel only; barrel nut, gas system, and handguard are sold separately.

Is this barrel legal to buy without paperwork? Yes, the barrel itself isn’t a regulated NFA item. Federal law only restricts how it’s used: it’s fine on a pistol-configured lower or a properly registered SBR, but installing it on an unregistered, stocked rifle lower would create an illegal short-barreled rifle.
