I've never seen one, and I've looked. The closest I've seen is to have a fixed choke barrel drilled and tapped for rem choke, or have the 870 tactical ghost ring sight barrel drilled and tapped for a rear rifle sight. (Though I'm not 100% sure the front sight is the same.)
Buying a barrel then having it drilled and tapped seems like a lot to shorten up my gun by 1.5". Though I'm sure I'll do it eventually.
