5.56 Nato 14.5'' 1-7 Hanson Mid-Lng Lopro Chrome-Line Thread

The Ballistic Advantage 5.56 NATO 14.5" 1-7 Hanson mid-length barrel is a precision-engineered cold hammer forged component built for shooters who demand accuracy and reliability in an AR-15 platform. This barrel combines Ballistic Advantage's proprietary Hanson profile with chrome moly vanadium construction and a phosphate finish, delivering the durability you need for repeated range sessions, defensive work, or hunting applications. The mid-length gas system strikes a practical balance between velocity and controllability, making it a proven choice for both 16-inch and shorter-barreled builds where you want consistent performance without excessive recoil impulse.

Built with a 1:7 twist rate, this barrel handles the full spectrum of 5.56 NATO ammunition—from lighter varmint loads to heavier match and tactical rounds. Every Hanson barrel is HP (high-pressure) and MPI (magnetic particle inspection) tested to catch internal flaws before they become problems downrange. The barrel features a cold hammer forged bore and chamber for superior concentricity and longevity, and the included pinned low-profile gas block seats securely on the 0.750" gas block journal without requiring permanent modification.

Threading is 1/2x28, so you can thread on a suppressor, muzzle brake, or flash hider to suit your mission. The Hanson profile tapers to a manageable weight (26 oz with the included low-pro block) while maintaining the stiffness you want for precision. One important note: Hanson barrels are not compatible with aftermarket piston kits, and they're designed specifically for .750" low-profile gas blocks—standard-profile blocks won't fit the gas block seat. If you're building an SBR or pistol configuration, federal NFA/ATF rules apply; consult those regulations before purchase.

Whether you're assembling a precision rifle, a duty-ready carbine, or a hybrid hunting platform, the Ballistic Advantage Hanson delivers cold hammer forged reliability without the premium price tag of match-grade barrels. This is the kind of mid-length barrel that runs and runs, accurate enough to trust when it counts.

Frequently Asked Questions

Will this barrel work with my aftermarket piston kit?

No. Hanson series barrels are not designed to be compatible with aftermarket piston systems. They are optimized for direct impingement with mid-length gas systems and included low-profile gas blocks.

What gas block does this barrel come with?

The barrel includes a pinned low-profile gas block. The gas block journal is 0.750", and only .750" low-profile gas blocks will fit the gas block seat—standard-profile blocks are not compatible.

Can I use this barrel for an SBR or pistol build?

Federal NFA/ATF rules apply to short-barreled rifles and pistols. This barrel can be legally used in a registered SBR, machine gun, or pistol configuration. Possession of this barrel with an unregistered short-barreled lower receiver is prohibited by federal law. Always consult current ATF regulations before assembly.

What ammunition does the 1:7 twist rate handle?

The 1:7 twist is a versatile rate that stabilizes the full range of 5.56 NATO ammunition, from lighter varmint and practice rounds to heavier match-grade and tactical loads.
