I have a Marlin 30aw 30-30 that I am looking to install a ghost ring sight system on. The problem I am facing is that the front sight on the 30aw is a dovetail post rather than the screw on ramp that the 336's use. The problem is it seems all the manufacturers of ghost ring sets assume the rifle has a ramp sight. So my question is, is there a rear ghost ring sight that will work with the current front post i have, or is there a set out there that includes a dovetail front sight rather than a ramp sight?
