I am going to build a peep-rail, similar to the EABCO product,for my Huntsman. The integral peep would be used for hunting [no scope in MN ML season] and the scope would be used to sight in and test loads. They would be both sighted in to the same spot. I will use a Williams 82 rail and extend the milled flat area to 1.5 ". This will take a flat bottomed WGRS with 1" hole spacing, and using 1/4 " longer mounting screws. The third NEF hole can use the standard length screw. The two mounting holes [13 /16" spacing] for the original rear sight can be used for a forward rail support if a shim is used to make up the receiver /barrel height differential. I will cut the Williams 82 to fabricate this rail segment after deciding which scope I'll be using so that I can get the best support with the least interference with scope turrets and bell housings.
