Corbin, Yes, you can use a barrel from an 870 Express with a 3" chamber on your 870 Super Magnum. From the Remington website: "NOTE: Model 870 Extra Barrels with 3" chambers will fit Super Magnum, Magnum, and 2-3/4" receivers. These barrels will handle both 2-3/4" and 3" shells when used on Magnum receivers
