The Ballistic Advantage 16" 5.56 HBAR Mid-Length Barrel brings serious durability to your AR-15 build without the extra weight penalty of a full rifle-length system. This is a heavy profile barrel purpose-built for shooters who want consistency and reliability on the range, at competition, or in the field. The mid-length gas system strikes a practical balance: it cycles cleaner than carbine-length and runs softer than rifle-length, making follow-up shots faster and the platform generally more pleasant to shoot, especially in a 16-inch package.
Built from Chrome Moly Vanadium steel and finished with a QPQ corrosion-resistant coating, this barrel is engineered to handle hard use and hold up to the elements. The 1/7 twist rifling is a modern standard that stabilizes everything from light 55-grain varmint rounds through heavy 77-grain match ammunition, giving you flexibility at the ammo counter. The M4 feed ramp extension is also QPQ-coated for the same corrosion resistance. Threading is 1/2x28, the industry standard for 5.56 suppressors and muzzle devices.
If you're assembling a general-purpose AR-15—whether for hunting, 3-gun, or a reliable duty rifle—this barrel delivers the accuracy and longevity that Ballistic Advantage is known for, without the premium price of a match-grade barrel. It's a smart, no-nonsense choice for builders who know what they want.

The 1/7 twist is a versatile modern rifling that reliably stabilizes 5.56 ammunition across a wide weight range, from light 55-grain rounds through heavy 77-grain match loads. This makes it a practical choice if you shoot different ammo types or want flexibility.
Yes. The 16-inch barrel length and mid-length gas system make this a solid option for hunting rifles, offering good velocity, manageability, and consistent accuracy from an HBAR profile designed to resist heat-induced shift.
Yes. The barrel is threaded 1/2x28, which is the standard threading for 5.56 suppressors and muzzle devices.
Mid-length gas systems position the gas port further back on the barrel, which generally cycles cleaner and produces less felt recoil than carbine-length systems. On a 16-inch barrel, mid-length is a practical middle ground that balances reliability with a softer shooting platform.
