Angstadt Arms AR-15 Threaded Barrel 9mm Luger 16" 1/2x36 Black

The Angstadt Arms AR-15 Threaded Barrel 9mm Luger 16" 1/2x36 Black is a medium-profile 4150 chrome-moly barrel engineered for 9mm AR builds requiring a suppressor-ready platform. This 16-inch barrel combines compact handling with velocity retention across 9mm ammunition loads, making it suitable for configurations where concealability, modularity, and sound mitigation are priorities.

Built from 4150 chrome-moly steel and finished with Melonite, this barrel resists corrosion and accelerated wear under extended fire cycles. The 1-10" twist rate stabilizes a wide range of 9mm projectile weights, from lightweight target rounds through subsonic loads used in suppressed applications. The 1/2x36 thread specification accommodates standard 9mm muzzle devices—flash hiders, muzzle brakes, and suppressors—allowing operators to configure the barrel for their specific mission profile. Chambered in 9mm NATO, it functions with standard military-spec ammunition and commercial 9mm Luger rounds. The integral 9mm barrel extension ensures proper magazine feed geometry and bolt face compatibility.

This barrel addresses builders and shooters developing dedicated 9mm AR platforms for suppressed training, close-quarters training, or reduced-noise practice. The 16-inch length balances velocity and maneuverability; 9mm cartridge velocity remains consistent across the 16-inch bore, and the medium profile reduces barrel deflection under suppressor-induced back pressure. Weighing 2.31 pounds, it maintains a practical balance for extended handling without sacrificing rigidity. Operators incorporating this barrel typically pair it with dedicated 9mm lower receivers and appropriate magazine systems, creating specialized carbines distinct from standard 5.56 AR configurations.
