Angstadt Arms AR-15 Threaded Barrel 9mm Luger 4.5" 1/2x28 BlaCK

The Angstadt Arms AR-15 Threaded Barrel 9mm Luger 4.5" 1/2x28 Black is a precision rifle barrel engineered for 9mm PCC (pistol caliber carbine) builds that demand lightweight performance and accuracy. Manufactured from 4150 chrome-moly steel and finished with Melonite coating for enhanced corrosion resistance, this barrel delivers the durability required for extended range sessions and field use while maintaining a profile optimized for weight-conscious builds.

At 4.5 inches in length, this threaded barrel maximizes velocity potential from the 9mm NATO cartridge while keeping overall platform length manageable for carbine handling. The 1-10" twist rate is calibrated for reliable stabilization across the full range of 9mm loads commonly used in PCC competition and training. The 1/2x28 thread pitch is the standard for 9mm suppressors and muzzle devices, providing broad compatibility with aftermarket sound suppressors, flash hiders, and muzzle brakes. The barrel extension is specifically dimensioned for 9mm, ensuring proper cycling and feeding reliability in AR-15 pattern lower receivers configured for pistol caliber operation.

This barrel is purpose-built for shooters running 9mm PCC platforms in competition, training, and recreational shooting environments. The lightweight profile reduces rotating mass and helps manage recoil impulse, which improves shot-to-shot speed and follow-up accuracy—critical advantages in timed stages and defensive scenarios. Angstadt Arms designed this barrel for pairing with their 4-inch ultra light handguard, though it remains compatible with any standard AR-15 upper receiver assembly. Operators and competitors who demand precision, reliability, and minimal platform weight will find this barrel a proven choice for serious PCC setups.
