I picked up 5 turk m38 mausers from SOG for $55 each. I was thinking of making one into a pseudo-scout. While looking for scope mounting ideas, I though aqbout just drilling & tapping the rear sight ladder for a section of picantinny rail. Does anyone know whether this will be stable? I see those mounts that replace the rear sight, but don't want to spend the cost of the rifle for a base if I can make a reasonable replica myself.
