Yes StrangerDanger is correct, I am hoping to replace some of the internal components of the collapsing stock. Right now there is some side to side wobble that I am not satisfied with. I am going to try replacing the retaining pin first and then the button if it comes to that. Thank you both for the pictures and instructions!

I recently acquired a Promag M4 collapsing stock and it seems like the retaining pin is a common point of failure on these. I have seen other posts here mention replacing the pin but I am unsure how to access the pin. Has anyone done this before? Pictures or parts guides would be greatly appreciated.
