Daisy Daisy 717/747 rear sight nut

sure not a problem
slotted screw head countersunk

factory fresh sight look at the nut

well they changed it the guns had felt wipers and they went to foam most have brass tubes but if you ordered a replacement they at the end they are aluminum
it is the way it is things change and who really care it is a nut

Just find a screw and nut that will fit.
