Ballistic Advantage BABL300011M Modern Series 300 Blackout 16" Black QPQ Finish 4150 Chrome Moly Vanadium Steel Material with DPR Profile for AR-15

The Ballistic Advantage BABL300011M Modern Series barrel is designed for AR-15 platforms chambered in .300 AAC Blackout, also known as .300 Blackout or 7.62x35mm. Built from durable 4150 chrome moly vanadium steel, this rifle barrel features a QPQ corrosion-resistant finish for enhanced surface protection and long-term durability. Its 16-inch length provides a versatile configuration for a range of .300 Blackout builds while maintaining the handling characteristics expected from a modern AR-15 barrel.
The barrel uses a pistol-length gas system and a DRP profile, with a .750-inch gas block journal for compatibility with appropriately sized gas blocks. A 1:7 twist rate is suited to stabilizing a broad selection of .300 Blackout projectiles. The rifled bore and threaded muzzle support a variety of compatible muzzle devices, helping builders configure the barrel to meet their specific platform requirements. This model does not include sights, making it a practical choice for custom builds using an optic or separate sighting system.
The feed ramp extension is QPQ coated to complement the barrel’s protective finish and support reliable cartridge feeding when properly installed with compatible components. As a Modern Series barrel from Ballistic Advantage, the BABL300011M is intended for builders seeking a dependable, purpose-built .300 Blackout option for an AR-15 rifle configuration. Confirm chambering, gas-system requirements, muzzle threading, and component compatibility before installation. Installation and headspace verification should be performed by a qualified gunsmith in accordance with applicable laws and safe firearm-handling practices.
