You can also stick your combo tool into the bolt face with the screwdriver face just under the extractor, push in to depress the ejector and turn clockwise to popt the extractor out. This works well to dissassemble the bolt, but its pretty hard to do in reverse to reassemble, as you need three hands to hold everything together and push the tool down to depress the ejector. You can either use a padded vice as a third hand, the .30-06 case in the chamber method, or the hari-kiri method of using your gut to hold the combo tool in place and pull the bolt into it while holding the firing pin and extractor in place with your two hands.
