Take your AR to a different realm with the Ballistic Advantage 14.5" 300 Blackout barrel. The 300 Blackout ranges from hard-hitting supersonics to heavy subsonic rounds. Because this round functions in a standard AR with just a barrel change, it is fast becoming a popular choice, especially for hog hunters. No need for a new bolt carrier group or different mags with the 300 Blackout. The 300 Blackout Modern Series 14.5" barrel is Mil-Spec.

BA takes the 14.5" 300 Blackout pistol-length barrel through the quench-polish-quench (QPQ) case-hardening process. This increases the corrosion resistance and lasts longer than the traditional chrome lining found in other barrels. The M4 feed ramp is also QPQ treated for the best performance. The muzzle is 5/8 x 24 threaded, so add a can to get maximum performance from the subsonic rounds. The Modern Series 300 Blackout pistol barrel uses a .750" gas block and weighs 27 ounces.
