I realize that there are a lot of posts about shotgun scopes, but I couldn't find a great answer to my questions. This is going to be my first year hunting and of course I have to hunt with a shotgun in my area.

I was planning on getting a Remington 870 with the smooth-bore/fully-rifled combo so I could do deer as well as geese or whatever. The question is: are "rifled sights" sufficient for a rifled barrel? Ideally, I should just go to the range and see if I can get a tight distribution with rifled sights, but I'm trying to figure this out before I make the purchase.

I'm also confused about the cantilever versus receiver scopes ... it looks like most of the 870 models don't have the receiver drilled and tapped for scopes, so I assume most people put up with the rifled sights.
