I have a 1187 step rib 12ga barrel that is 30in long and comes with two rem choke. This is the big bore, .740 and choke are full, ext full. The barrel was made by Remington in the late 80s for trap and is in very nice condition. I had this on my 1100 comp and it worked just fine. I sold the gun and no longer need barrel. $250. shipped
