I just bought a 1966 Marlin Mountie at a gun show this weekend. The front sight is ridiculously short, way to short to use with the Williams FP I just put on it. Does anyone know whether the front sight dovetail is the standard 3/8"? It looks smaller to my eye, but it could be an optical illusion. I definitely want to replace the front bead with a taller sight, maybe a Brockman's Patridge style post. I have had good luck with the Marbles 1/16" ivory bead as well. Any recommendations?
