Ballistic Advantage 5.56 NATO 16" HBAR Mid-Length Barrel 1:7 Twist – AR-15 Platform

This 16-inch heavy barrel profile from Ballistic Advantage delivers enhanced rigidity and heat dissipation for sustained strings of fire. The mid-length gas system reduces felt recoil and cyclic rate compared to carbine-length systems, improving controllability and extending component life. The 1:7 twist rate stabilizes bullets from 55 to 77 grains, making this barrel well-suited for both general-purpose and precision-oriented AR builds.

Constructed from 4150 Chrome Moly Vanadium steel with a black nitride finish for corrosion resistance and bore longevity. The barrel extension is properly indexed and torqued, with M4 feed ramps for reliable feeding. Compatible with standard AR-15 upper receivers and mid-length handguards. Includes a .750" gas block journal. Professional installation and headspace verification recommended.
