well the vote went with park it all, so I did. first thing I did was to remove the gas piston. Before I did anything i measured from the fromt of the carrier to the end of the piston, this way when I put in the new piston I can put it back to the same length. Next I drilled a little into one side of the pin, then used a punch to drive the pin out. took the fire pin out and then took out the extractor from the bolt. As advised to protect the springs. here are the parts degreased and ready to cook.
