Great little barrel! by FreemanActual, Verified Owner, November 3, 2022

Product Info for CBC Industries 300 AAC Blackout AR-15 Barrel, 5/8x24, 1-7, Micro

The barrel is one of the few components that directly affect the accuracy and weight of your build. This barrel has a nitride finish for increased strength and durability. This provides not only an impressive barrel life but ensures excellent accuracy. The barrel threads are carefully threaded to the .308 standard. Optimized for stability with a 1:7 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease.image
