Description
This Diamondback 556P55H50B8R brings quality engineering to your AR pistol build with a heavy profile that resists heat and harmonics better than pencil-thin alternatives. The 4150 chrome moly vanadium steel with black nitride finish handles full-power loads without flex, while the 1:8″ twist stabilizes both standard 55-grain rounds and heavier match ammunition. At 5.50″, it’s purpose-built for pistol-length systems where you need accuracy without sacrificing maneuverability. Whether you’re building a compact home-defense rig or precision 300 blackout upper, this barrel delivers the durability and accuracy that serious shooters expect.
