On occasion, when disassembling for cleaning, I often have problems stripping the flats on the cleanout plug. Is there a special small screwdriver to take these out. I usually get a couple of years out of a plug before it gets bad. But last night after going to the range, the plug was really stuck. After just about messing it up and a lot of cursing, I finally got it out, but the flats on plug are deformed and stripped so I have to buy another one. Anyone have a trick they can share? How did a mountain main take this plug out 160 years ago in the wilderness?
