    FN 5.7 threaded barrel

    Fit and finish is beautiful. The thread adapter to ½-28 fits nice but locks into suppressor and threads off the barrel. Would be nice if it had a cut out that fit a wrench to separate easier...Overall very happy

    Great Barrel

    Great drop in barrel for the FN57, purchased two of them so far and they have always worked great, the one I purchased back in Jan 25 of 2020 is still looking strong internally and out.
