I just replaced the factory HiViz optic sights right ghost ring sights. The problem is that the rear sight that was on there was mounted on there is gone with an unappealing visible notch on the barrel. So I want to get a small rail to mount ahead of action where the old rear sight used to be. I have another marlin that already has the XS scout scope rail, and want something a bit smaller. but all the other rails seem to mount ontop of the receiver which is where my ghost ring sight is now.
