Crafted from 4150 CMV steel, this barrel features a Salt Bath Nitride finish inside and out, ensuring exceptional corrosion resistance, longevity, and smooth bore surface for consistent performance. The Big Gunner profile tapers weight forward of the chamber while maintaining thermal mass at the back end, effectively managing heat and minimizing barrel whip for sustained accuracy.
With a 1:10 twist rate, it is optimized for a wide variety of .308 bullet weights and configurations. The barrel is threaded 5/8x24, making it suppressor- and muzzle device-ready, and includes an 11-degree target crown to enhance precision. It uses the LR-308 barrel extension, making it compatible with DPMS-style AR10 platforms.
