Does anyone know the best place to buy part of an 870? When I bought my 870, it came with two barrels. I use the slug barrel for deer and when I put a scope on it, it made it very difficult to remove the barrel (would involve taking the scope and rings off).

So I am left with a bird barrel. Now I'm either looking at selling the barrell or buy the rest of an 870 for my barrell. Does anyone know if this is possible? If so, where? and how much do they run? Thanks
