When I got my first Marlin I had the same problem. The solution I went with is the following:
Williams FireSight front bead. Settles right down into the rear notch, highly visible, works great.
Marlin "cut-out" front hood. About $5 delivered from Marlin. The cut-out allows light to hit the FireSight, yet still protects it. Otherwise you need to remove the hood for best results with the FireSight.
Warne "Maxima" Quick Detach bases and rings. Allows me to shoot glass or iron as I choose.
Leupold VXII 2-7x33 scope. Relatively compact, still looks good when mounted.
