    Great barrel

    I received my barrel quickly and as described. I doubt anyone will find a better threaded barrel for a sig p320 m18 for this price... trust me I looked for a while. It looks great, dropped right into my sig m18 no problems. Picked up a little extra accuracy it seems like . Can't wait to get a compensator the hole readon why I bought this particular barrel and for the price of course.
