Ok I was shooting pretty well with my nagant m91/30 rifle...I did a few minor mods,polished the part of the firing pin that rubs up against the inside of the bolt,polished up surfaces that make contact with the receiver.Now...I want to be able to clean up the trigger surfaces.Heres my problem,the screw for the trigger leafspring is Rocksolid...wont budge.I boogered up the screw a little so i stopped.Now how do i get this thing out.Oh yeah and its not that boogered up Im going to get some quick blue and sandpaper and fix it up .But how do I get the screw out?
