I've been pondering the sight question for a while now. There are some fiber optic front sights available that replace the front bead. The back sight one might have to make an adapter plate that mounts to the scope mounting points but that would probably be too high for a drop in front sight so you would have to put a spacer on the front sight to raise it up to match.
I think Optics Planet has a picanty rail that mounts to the scope mounts which might be a starting point.
My other thought for the front sight is to get a figure 8 shape piece machined to go around the barrel and hold a light underneath. The part that goes around the top of the barrel would have a mount for a sight.
Or just cough up the money and put a holographic or red dot on top and call it good.
