    CENTURION ARMS MK11

    Posted by Eric Anderson on Jun 22nd 2026

    The customer service Andrew provided was second to none. I have never worked with a gun dealer online as kind and knowledgeable. You will not be disappointed. This will be my second Centurion Arms MK11 upper and Lower, the fit and finish is amazing. The gun feels so solid but not overly heavy. I have built several AR10 platforms, this has been the best brand and fit and finish I have seen, worth every penny!!
