Hi, I am going to rebuild my 1st reg on Impact M3. But FX diagram is not provided for it. How do you know what o-ring to order? Anybody has a list of all o-ring for this part?
Mubhaur Any chance to post the sizes of the piston , I have access to a cnc lathe and would like to see how it goes making a piston , but I don't want to pull my gun apart just to measure Drawing would be even better if u have one
