So, I just bought a PSA gen III pa10 lower and paired it with my M5 aero precision upper and the only problem I encountered was that the rear takedown pin was too tight to work properly without using a tool to get it in and out. I feixed this with a different method than above. I was able to use a dremel and ever so slowly widen both the backside hole on the PSA lower and take a little off the AP upper and now it fits perfectly. It keeps the upper tight but it is able to be pushed in and out using just my thumb and fingers as it is supposed to be. There is still the small gap in the buffer section. Im waiting for the last parts to come in so I can complete the build and take it shooting. I'm curious how it went for you. I posted a youtube video showing the final product.
