Hey, fellas, my favorite lil' rifle may have a sight issue. Almost immediately after I purchased my .45-70 a couple years ago i installed a willaims receiver or 'peep' sight in the rearmost location on the barrel. While sighting it in at 75 yards a noticed that the peep has to be set back in almost the "lowest" position on th ramp. Hasn't really been an issue but i was wondering if that means I need a taller blade up front? If so, where could i obtain one? Thanks in advance, guys.
