Description
This 7.5” barrel is crafted from durable 4140 steel and chambered in .300 AAC Blackout, making it a solid choice for AR pistol or compact SBR builds. It features a 1:8 twist rate to stabilize a wide range of bullet weights and a .750 gas block diameter for compatibility with standard components. The 5/8x24 thread pitch supports suppressors or muzzle devices, while the pistol-length gas system ensures reliable function, especially with subsonic loads. Finished in a classic parkerized coating, this barrel combines performance and rugged durability in a compact platform.
