Hey i am shopping around for a slug gun. i want to stick with remington. I was looking at the rem 870 superslugger. that is a 870 synthetic with the cantilever scope mount built in on it. my question is, is that gun worth the extra money or should i just get a regular 870 synthetic. the super sluger is 500 and the regular 870 express sytnthetic is like 300. i thought the cantilever scope mount would be better because i could buy another barrel and be able to not worry about the scope being in the way. thanks
