Geissele 8" Cold Hammer Forged 300 Blackout Chrome Lined AR-15 Barrel 1:7 Twist

Geissele Automatics Rifle Barrel Features The Geissele Automatics Rifle Barrel is precision machined and cold hammer forged from chrome moly vanadium steel at Geissele s North Wales Pennsylvania facility to ensure consistency from barrel to barrel. Its 8 length and Geissele taper profile are matched to a custom pistol length gas system and .750 gas block diameter for reliable cycling in a shorter host rifle. A 1:7 twist rate stabilizes heavier .300 AAC Blackout projectiles commonly used for both supersonic and subsonic loads. M4 feed ramps extend into the barrel extension to smooth the transition from magazine to chamber reducing the chance of a feeding malfunction under rapid fire. Every Geissele barrel is High Pressure Tested and Magnetic Particle Inspected before it leaves the factory giving builders confidence in both accuracy and long-term reliability. The bore is chrome lined for corrosion resistance and easier cleaning while the exterior wears a manganese phosphate finish in black for additional durability. A 5/8x24 thread pitch accepts a wide range of muzzle devices and suppressors and the barrel ships complete with a matching gas tube and gas block. This combination of material quality and finish work makes the Geissele Rifle Barrel a strong choice for a hard-use duty weapon or a precision-tuned competition build.
