    When will this be back in stock? If I buy the upper kit and barrel separately it’s more expensive, but they are in stock. That makes no sense.

    Does this barrel run as smooth as a barrel of the same length but with a mod length gas system?

      The barrel will be smooth due to the RF85.
      Now comparing to mid length not sure.
