i am selling a nice mx-10 unsingle barrel trap gun. it has a 34" factory choked barrel, .737 bore with 32th choke, that has been pro-ported. it has the 18.7 stamped on the barrel. it comes in a perazzi combo hard case. this would make someone a very nice shooter. price for the perazzi mx-10 is $6800.00 plus shipping and insurance to your ffl dealer.
