Tom,
Thanks for the picture and the measurement. I'll just have to see what I can find that works. If Cabelas doesn't have what will work then I'll try Sportsman's Warehouse or one of the local shops here in Phoenix and see what works. I really didn't think about changing the rear sight and will look into that also.

It might boil down to me having to have the holes re-drilled and tapped so the larger Torx screws will work but what really bothers me is that the screws wouldn't even go through the factory drilled holes in the Leupold base. But that will get worked out one way or another.

Thanks again,

Barry
