Ballistic Advantage BABL556015M Modern Series 5.56x45mm NATO 16" Black QPQ Finish 4150 Chrome Moly Vanadium Steel Material Midlength with Government Profile for AR-15

The Ballistic Advantage Modern Series BABL556015M barrel is designed for AR-15 builds chambered in .223 Remington and 5.56 NATO. Its 16-inch midlength Government profile provides a balanced platform for general-purpose, tactical, and recreational applications while maintaining compatibility with standard midlength gas system components. The rifled bore features a 1:7 twist rate, making this barrel well suited for stabilizing a broad range of commonly used 5.56 NATO projectiles.
Constructed from 4150 Chrome Moly Vanadium steel, this Ballistic Advantage barrel is finished with a QPQ corrosion-resistant treatment for added durability and long-term protection. The barrel includes a QPQ-coated M4 feed ramp extension, helping support reliable cartridge feeding when paired with a properly assembled upper receiver. Its threaded muzzle allows for the installation of compatible muzzle devices, giving builders flexibility when configuring their AR-15 platform.
The BABL556015M uses a standard midlength gas system and is built with a Government profile for a practical balance of strength, weight, and handling. It does not include sights, making it a suitable choice for custom builds that use a preferred optic, backup sight system, handguard, or muzzle device. Whether used for a new upper receiver assembly or as a replacement component, this Modern Series barrel delivers a durable foundation for a dependable .223 Remington or 5.56 NATO rifle. Professional installation and proper headspace verification are recommended before use.
