Hallo Kano
Yes, I need to remove the flip up island sight..I will mill another substitute to fill the gap and store my sight. I already measured the gap from the surface of the cocking piece..it is seven millimeters in height, not much to work with ...Kano, I know of a Lyman 36 sight available for purchase, if you are interested I can forward you the details...I will be back next week and start with the sight building project. Please keep me up to date with your experiments .
