View Full Version : Question for folks with Rem 870 HD guns

April 22, 2009, 06:31 PM
What is the O.D. of your barrel at the end where a sight would be mounted? I want to get a set of ghost ring sights, or any rifle sights for that matter, but the only ones that have a clamp-on front sight are for the 870. Can these be made to fit a Mossy? What's the difference if not?
