Here you go ! This really helped me the first time, now it's a charm to do it.

Take the sharp end of the pick in your cleaning kit and compress the extractor detent until it clears the extractor. This takes two hands so use your thir.... tip the bolt over and wiggle it to get the extractor to fall out. If it doesn't go, yell at it until it does. Then release the pressure on the detent and remove it along with the spring. The firing pin will now fall out the back of the bolt. Reassembly is the reverse except you yell at the extractor AND detent at the same time.
