Ballistic Advantage 16" 5.56 NATO Performance Barrel, 1:7 Twist, Hanson Profile w/ Low Profile Gas Block (.625)

Building a reliable 5.56 AR platform starts with a quality barrel, and the Ballistic Advantage 16" 5.56 NATO Performance Barrel with Hanson Profile is engineered for shooters who want accuracy, durability, and practical handling. This 16-inch barrel is machined from 4150 Chrome Moly Vanadium steel and finished with a QPQ corrosion-resistant coating—a proven combination for consistent performance in duty, competition, or hunting applications. The .625" Hanson profile balances firearm weight and thermal mass, making it lighter and more maneuverable than heavier barrel profiles while still managing heat during sustained fire.

What sets this barrel apart is the pre-installed low-profile gas block. Ballistic Advantage pins the block in place and includes an extended M4 feed ramp extension with Nickel Boron coating, so you're ready to assemble without sourcing additional parts. The mid-length gas system and 1:7 twist rate make this barrel a versatile choice—the faster twist stabilizes heavier projectiles (up to 77-grain) while still cycling standard 55-grain loads reliably. If you're running a piston operating system, note that Hanson barrels are optimized for direct-impingement setups and aren't designed to work with aftermarket piston kits.

Whether you're putting together a fresh build or upgrading an existing upper receiver, this Ballistic Advantage barrel delivers the fit, finish, and value that come from buying a matched barrel-and-gas-block assembly rather than cobbling components together. It's the kind of smart choice that separates a dependable rifle from a collection of compromises.

Frequently Asked Questions

Is the gas block included and installed?

Yes. The low-profile gas block comes pre-pinned to the barrel, so you don't need to source it separately or deal with installation alignment.

Will this barrel work with a piston system?

No. Hanson barrels are optimized for direct-impingement (DI) operation and are not designed to work with aftermarket piston kits.

What twist rate does this barrel have, and what ammunition does it stabilize?

The 1:7 twist stabilizes heavier projectiles, including 77-grain rounds, while also reliably cycling standard 55-grain loads.

Is this barrel suitable for an AR-15 build?

Yes. This 16-inch barrel is a standard AR-15 profile and integrates into any direct-impingement upper receiver assembly.
