Once upon a time before the rifled barrels took over the slug barrel market, Remington made a lot of smoothbore slug barrels with rifle sights. I still have one here that came on my 870 "Special Purpose Deer", 12 ga. that has now has had a fully rifled Remington barrel on it for over 20 years. Don't know what the market is like these days on used shotgun barrels but it might be worth investigating. Here's the smoothbore 870 barrel with rifled sights, Forgot the choke constriction but I'm pretty sure it's Cylinder Bore. Have no idea what these go for nowadays but if they are out there you could find out.
