I bought a Lyman 48 WJS sight to see how it would go and had it sent to the gunsmith. Yesterday he kindly sent me the following pictures and this comment.
“The sight will work out pretty good with minimal modification. The only thing that needs to be changed is the thickness of the knurled release knob to clear the bolt handle…piece of cake.
This picture shows the area I will cut down. In this photo the lock knob is not screwed down solid and locked yet. When it is locked down in the ready-to-use position there is only about .030” interference.”
It looks like I may have a workable solution for now. The action came from the factory drilled and tapped for normal scope mounts. I will probably have a single square bridge welded to the rear and the Lyman mount base contoured to mate it. The front receiver ring holes will be filled with plugs and the receiver ring stippled to hide the work. AR has photos of a Dakota action Duane Wiebe did this way and the plugs are invisible.
I'm still exploring options at present but it looks like I'm getting close to a decision.
cheers,
