The Angstadt Arms AR-15 Threaded Barrel 9mm Luger 4.5" 1/2x28 Black is a precision rifle barrel designed for 9mm PCC (pistol caliber carbine) builds that prioritize lightweight performance and accuracy. This barrel is ideal for shooters engaged in competition, training, and recreational shooting, offering a balance of durability and performance.
Manufactured from 4150 chrome-moly steel and finished with Melonite coating, this barrel enhances corrosion resistance and durability, making it suitable for extended range sessions. At 4.5 inches in length, it maximizes velocity potential from the 9mm NATO cartridge while maintaining a manageable overall platform length for carbine handling.
The 1/2x28 thread pitch is the standard for 9mm suppressors and muzzle devices, ensuring 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.
