      These barrels should be broken in. Doing so will help your barrel perform consistently over its lifespan. To break it in, simply

      1. Shoot 25-40 rounds
      2. Clean the bore
      3. Inspect the gas block to ensure it is still attached securely. Inspect the Bolt for unusual signs of wear.
      4. Repeat the above steps four more times.
