Why This Barrel

The mid-length gas system reduces felt recoil and extends component life compared to carbine-length systems. The 18-inch length provides excellent velocity while maintaining a compact, maneuverable profile. The 1:7 twist is the modern standard, reliably stabilizing everything from 55-grain varmint rounds to 77-grain match ammunition.

Whether you're building a precision rifle or upgrading an existing platform, this barrel offers the performance and reliability that discerning shooters expect.
