I just removed mine last night in preparation for the springs I ordered from GreTan. Push down the plunger under the extractor with a very small flat tip screwdriver. After that pull the extractor out and up at the same time. When it comes free the plunger and spring will fly far so a plastic bag over the works would be a good idea. It's a little fiddly and much easier to put back in than take out. Be careful not to scratch the bolt body.
