RE: Remington 870 supermag w/ scope
Another option for Remington is buy the choke tube cantelever barrel. It is 21 inches - comes with a rifled choke tube for slugs which all you do is take your current turkey choke and replace the rifled choke. I got my barrel in matte -so no need to camo.
Now what that does - I have a turkey gun, a deer slug gun and going back to the original 26" barrel I have a duck and pheasant gun.
Just another idea.
