No screw holes needed on that bottom one, the Miller Kodiak Mount.  I have one on my cutdown 92/96.  I did add two screwholes on the barrel to hold a removeable dovetail, rather than have a dovetail cut directly into the barrel.  Over the center interferes with case ejection, but I don't mind.  If I need a rapid fire rifle, I'll take something else.  I think a receiver sight mounted where the OP indicated the holes are might also interfere with ejection.
