Ballistic Advantage 5.56 NATO 16" Classic Series Barrel – AR-15

The Ballistic Advantage 5.56 NATO 16" Classic Series barrel delivers reliable performance for general-purpose AR-15 builds. This government profile barrel is chambered in 5.56 NATO (also accepts .223 Remington) and provides the accuracy and durability expected from a mid-length gas system configuration. The 16" length meets legal rifle requirements without requiring NFA registration, making it a practical choice for range use, competition, or defensive applications.

Manufactured from 4150 Chrome Moly Vanadium steel with a QPQ Nitride finish, this barrel resists corrosion and wear while maintaining heat dissipation during sustained fire. The barrel extension is properly torqued and pinned, and the chamber is stress-relief mapped for consistent headspacing. Compatible with standard AR-15 upper receivers and accepts .750" gas blocks. Mid-length gas system reduces felt recoil and bolt carrier velocity compared to carbine-length systems.
