[QUOTE="J E Custom, post: 1421223, member: 2736"] The reason I originally posted bolt face diameters was to help choose the cartridge that would fit the existing bolt face diameter to avoid altering the bolt if possible. Opening up a bolt face and replacing the extractor is common and very doable for a quality gunsmith. but reducing a bolt face diameter causes many problems and could possible damage the bolt beyond repair. I don't recommend applying heat (Welding or soldering) to any bolt face because it can alter the heat treat in the most important part of the bolt and recoil lugs. In my opinion, it is best to replace the bolt with a new one or a good used one with the correct bolt face diameter. new bolts are normally about the same price as alteration to the old bolt and far less risky. Even after the proper bolt is used there may still be major alterations That need to be done to the feed rails and/or the magazine box for proper feeding, so in my opinion it is best to stay with a cartridge that is similar to the original cartridge if possible. Most of the time, the simple solutions are the best. J E CUSTOM [/QUOTE]
