Ballistic Adv BABL556015M Modern Series 5.56x45mm NATO 16" AR-15 Barrel - Midlength Government Profile - Black QPQ

The Ballistic Adv BABL556015M is a 16-inch 5.56x45mm NATO chambered barrel built for the AR-15 platform and part of the value-driven Modern Series. Machined from 4150 Chrome Moly Vanadium steel and finished in a corrosion-resistant Black QPQ coating, this barrel pairs a government profile contour with a mid-length gas system for reliable cycling across a wide range of 5.56 NATO and .223 Rem ammunition.

Chambered in 5.56 NATO (which also safely accepts .223 Rem rounds), the barrel carries a 1:7" twist rate and a rifled bore for consistent accuracy whether you're running a tactical carbine, a duty-grade rifle, or a general-purpose range build.

The government profile contour is paired with a mid-length gas system set up for a .750" gas block journal, and includes a QPQ-coated M4 feed ramp extension for smooth, reliable feeding. The muzzle is threaded 1/2x28 for standard 5.56 muzzle devices and suppressors, and the barrel ships with no sights installed, allowing you to configure your preferred optic or iron-sight setup.

Designed as a direct-fit replacement or upgrade barrel for the AR-15 platform, the BABL556015M Modern Series barrel brings Ballistic Adv's blend of accuracy, durability, and affordability to your next build.
