Remington 870 Super Slug Deer Barrel?

just got a fully rifled Remington super slug deer barrel for Christmas. It comes with a no-name 2-7X scope mounted on a cantilever rail. i called remington and they said the scope was crap, so i was thinking about exchanging it for a fully rifled express barrel with a cantilever mount and using the difference in price to put towards a scope. thing is, ive heard from several online comments that what makes it "super" is that the super slug deer barrel is a beefed up, heavier barrel then the normal express rifled barrels (which i really like given that i will be shooting 3" magnums out of a pump). BUT i cant seem to find any of the super slug deer barrels without the scope attached. does anyone know if they make them? since i want the heavy barrel, if they dont, ill just take the scope off and buy a different scope, but if they do, ill return mine and get a super slug with no scope and put the money towards a good scope for it.

anyone know?
