Diamondback Barrels 5.56 16" Hbar Mid 1/7

The Diamondback Barrels 5.56 16" Hbar Mid 1/7 is a mid-length gas system rifle barrel chambered in 5.56 NATO, engineered for the AR-15 platform. The 16-inch barrel length balances velocity retention with overall weapon handling, while the 1/7 twist rate stabilizes the full spectrum of 5.56 ammunition—from lightweight 55-grain rounds to heavier 77-grain loads—making this barrel suitable for everything from training and competition to patrol and defensive applications.

The H-profile barrel designation indicates a heavier contour than standard government profile, which reduces harmonic vibration and improves accuracy at distance while maintaining adequate heat dissipation during sustained fire. Mid-length gas systems are known for softer recoil impulse compared to carbine-length systems, allowing faster follow-up shots and better control in rapid-fire scenarios. This configuration is the practical centerpiece of a reliable 5.56 rifle build for shooters prioritizing consistent performance across varied ammunition types and shooting conditions.

This barrel appeals to AR-15 builders and end-users assembling precision or duty-grade rifles who need a proven mid-length platform with proven accuracy and reliability. The 16-inch length keeps the overall rifle length manageable in vehicles and confined spaces while delivering near-carbine velocity. Whether building a home defense rifle, competition gun, or general-purpose tactical carbine, the Diamondback 5.56 16" Hbar Mid 1/7 serves as a solid foundation for a dependable AR platform.
