The Ballistic Advantage Super-Shorty AR-9 Barrel solves the challenge of creating an extremely compact defensive pistol-caliber carbine without sacrificing accuracy or reliability. At just 4.5 inches total length, it delivers ballistic performance equivalent to full-size handguns while providing the superior handling, accuracy, and modularity of the AR platform. The integrated barrel extension eliminates the complexity of separate components while the blowback operation requires no gas system, simplifying builds and reducing weight. This specialized barrel enables defensive AR-9 builds that excel in confined spaces, vehicle operations, and situations requiring maximum maneuverability without compromising on precision.
Note: Requires magwell conversion for Colt/Rock River style with UZI magazines or dedicated 9mm lower for Glock magazines. Ensure 9mm rounds drop freely through any muzzle device before installation.
