I have a beautiful Perazzi MX8 35" Top Single barrel. It is non-ported, has a 11x7mm tapered rib, an 18.7 bore, 1.66 kg weight, and Full Choke (0.033). SN# 125xxx and a 2002 manufacture. As you can see from the pictures, the bluing is perfect everywhere. There is not even marring at the forearm location. Bore is perfect as well. I bought this barrel new and have shot approx 1,000 shells thru the barrel. It turns pigeons into dust. It has been sitting in my gun safe and needs to go to someone who will shoot this great barrel. Will ship in lower 48 for $1750. No trades.
