Remington 870 XCS Marine Magnum (with the factory black TriNyte corrosion control system), Vang Comp oversized safety, Vang Comp steel follower, Wulff recoil spring, and Wilson Combat +2 extension. It has the SpeedFeed stock with the 2-round storage in each side (4 rounds total in the stock). It's had probably 200rds of those #8 shot bulk-pack Walmart loads through it at the trap range (probably the wrong tool for the job but it was fun). I've had my shoulder rebuilt twice and recoil isn't pleasant anymore so this needs a new home. $650 shipped to your FFL dealer. PM if interested.
