Description
The 20" .224 Valkyrie Spiral Fluted Upper Assembly is purpose-built to take full advantage of the Valkyrie’s long-range capabilities. Featuring a spiral fluted, nitrided 20" barrel with a 1:7 twist, this upper is optimized with a rifle-length gas system, precisely tuned for the Valkyrie’s pressure curve. The American-made M-LOK handguard, nitrided steel gas block, and properly installed components ensure sub-MOA accuracy and smooth function right out of the box.
Unlike budget builds, this upper uses SAAMI headspaced barrels, precision torque specs, and AEROSHELL 33MS anti-seize + Permatex 242 for long-term reliability. The medium spiral fluting sheds weight without sacrificing stiffness, improving heat dissipation, and maintaining cold-bore accuracy. Designed for shooters pushing beyond 1,000 yards—without stepping up to an AR-10.
