I have a new, unfired Remington 870 Express 3" Magnum, 12 gauge, it has screw in choke. I have had this for quite some time and frankly forgot about it in the back of the closet. Super like new condition, 30" barrel. Possible trades, ask first...$475.00, i will ship on your dime or come and get it and save all the paperwork. good luck
