I have an idea for correcting the sight picture of a gun with too little drop at face. The neccesity for this idea came from the ownership of three English guns, none of which I want to bend or shave. If you (or I) need to lower the stock 1/4 inch, we make a pair of Boss style short ribs, with magnetic inserts, to raise the effective sighting plane of the rib. I haven't made my ribs yet, but am preparing to get started. I have sighted over Boss style quarter ribs and find them very comfortable.
