This friday I picked up a lee-enfield no.4 mk.1 in fairly good condition. I have yet to take it to the range, but I noticed the rear sight peep hole only moves up 1/4 of the total range it should. Upon closer inspection i saw that the screw that the peep sight block (? i don't know the technical term

) rides on is bent slightly. I could try to bend it back into place, or should I just go out and get a completely new rear leaf sight. Any ideas??
