Lot different animal than an 870. I don't think the barrels come off. Remove the butt stock, then remove the trigger group. The butt stock screw pulls on the trigger group, and makes removal of the screw and pin that hold it in place, difficult if not impossible. Then slip the action bar out of the bolt, and the bolt should drop out the bottom. I'm going from memory here, so your mileage may vary!! Take pictures as you go to make reassambly easier.
