What is the differences between the Remington 870 SPS-T Super Magnum Camo and the 870 Express Super Magnum Turkey Camo. I see the list price of the SPS-T is $186 more. The only differences I see is the included camo sling, the camo foreend sling mount, the super full turkey choke and the different camo pattern. That's can't be work almost $200.
