I have a Remington 870 Express 12ga. It has the short field barrel with an improved cyl choke & a turkey choke. Both are factory Remington chokes. The slug barrel is a 24" fully rifled Mossberg barrel. I had the receiver drilled & tapped & will leave the scope rail on the receiver. There is some minor surface rust on the outside of the slug barrel. Nothing is wrong with the bore. I purchased the gun new in 1989 & have only used for deer hunting & a couple of turkey hunts. It has the factory plug in the magazine. I will include what slugs I have and any shot shells. I'm asking $300 & that's firm. If you want more info just let me know.
ps. Thanks to "our" new lab pup, the front edge of the box is a little ventilated.
