I found this on you tube. I was working on mine today. I drilled out the indention just to the threads, put the old piston in a vise and spun it out. Now I want to find a tap to clean up the treads. Need to do some research on what size the tap is. Then I will follow the same as the guy in the video.

I called a local gun shop and they told me as long as I change enough parts to be 922r compliant I can do it. I also have been reading posts on calguns to see if any info on it. They are posting pic's configured the way I want, but need to double check. Thanks for the info.
