Wow!
I have never run into this problem but perhaps the following is an idea?
- put several drops of oil on top of the spring guide for lubrication.
- place the breech block, surrounded by a soft cloth, in a small vise, tighten down just enough to hold the part firmly,
- use needlenose players to grip the spring guide from the side slot and work it out.
Or place one plyer needle against the top of the firing pin, the other on the underside of the spring guide and open the plyers?
Just an idea.
What went in, should be able to come out....
Another idea: heat the breech block from the outside under very hot water- should cause it to expand, reducing the pressure on the jammed spring guide, then grip the guide from the side with plyers and extract?
Hope the side button on the guide is not damaged... or the inside of the breech block....
