    Nora’s C ported barrel

    Posted by Michael on May 26th 2026

    This barrel, in copper finish, not only finishes this build with a touch of class but is a great shooting barrel! The ports keep the weapon settled in your hands with minimal muzzle rise decreasing time between shots and also appears to be a more accurate barrel than the stock barrel. All in all I’m very happy with my first Norrso project.
