The Angstadt Arms AR-15 Threaded Barrel 9mm Luger 6" 1/2x28 Black is engineered for shooters building a dedicated pistol-caliber carbine or large-format pistol where compact maneuverability is the primary objective. This 6-inch barrel provides a significant advantage for home defense and tactical operations, offering a footprint that excels in tight quarters while maintaining superior ballistic efficiency.

Constructed from 4150 chrome-moly steel, this barrel undergoes a Melonite finishing process to ensure exceptional surface hardness and long-term corrosion resistance. The 1-10" twist rate is specifically optimized for stabilizing a wide variety of 9mm projectile weights, ensuring consistent accuracy during rapid-fire sequences. Featuring a lightweight profile, it minimizes front-end weight to improve target transition speeds without compromising barrel harmonics or structural integrity. The standard 1/2x28 thread pitch allows for the seamless integration of suppressors and muzzle devices, which is critical for signature reduction.

This barrel is purpose-built for compatibility with the Angstadt Arms 5.5" ultra-light handguard, creating a flush and professional aesthetic for custom tactical builds. Those looking to buy a reliable 9mm barrel will find that the integration of the 9mm Luger chambering ensures broad ammunition compatibility from training rounds to duty loads. Installation is straightforward on standard AR-15 upper receivers designed for blowback or specialized 9mm operating systems. For those reviewing specifications for their next sub-compact build, this barrel offers the perfect balance of durability, weight, and tactical utility.
