BTW - Make sure they don't hammer the piston rod - but use a lever to push & straighten it.

Re: problem with IHP piston
My friend had the same problem, so took it to the lathe and that was a old man doing the job he just removed the center sear rod and refitted it in correct position after straightening it, with the help of making a thread to fit it.
Now the gun has crossed over 2000 shots without any problem.
