6.5 Grendel 12.5'' 1-8 Twst Hanson Cont. Carbine Bbl W/Lo Pro

The Ballistic Advantage 6.5 Grendel 12.5'' 1-8 Twist Hanson Carbine Barrel with Lo-Pro Gas Block is built for shooters who demand a lightweight, accurate platform without the weight penalty. Machined from 416R stainless steel and finished with a bead blast, this barrel handles the moderate recoil impulse of the 6.5 Grendel cartridge while maintaining the rigidity needed for consistent hits downrange. The Hanson profile—Ballistic Advantage's proprietary design—delivers the weight savings you want in a short-barreled setup while keeping the accuracy you need for hunting or precision rifle applications.

This barrel comes configured with a pinned low-profile gas block, eliminating one more sourcing decision and ensuring reliable function out of the box. The 1-in-8 twist rate is the right call for the 6.5 Grendel, stabilizing the wide range of bullet weights commonly loaded in this cartridge. At 12.5 inches, you're looking at a true short-barrel build—ideal for close-range hunting, truck guns, or any setup where maneuverability matters more than velocity. The bead-blasted finish provides a clean aesthetic while resisting corrosion.

Worth noting: this barrel is engineered around Ballistic Advantage's direct impingement design philosophy and is not compatible with aftermarket piston conversion kits. If your build plan relies on a piston system, you'll need a different barrel. For hunters and shooters committed to a gas-tube platform, however, the Hanson profile delivers a balance of weight reduction and structural integrity that keeps groups tight.
