It wasn't the metal that broke, the plastic buffer itself snapped in half right where it meets with the metal rod. A roll pin goes through the metal rod and they holds the buffer in. I did not use any tools or anything like that and just simply was removing the bolt with my fingers. I don't know how to post pictures on this forum but I do have one crappy photo. I know I'm not the only person this has happened to as I found a video of another guy this happened to. Looking at the design any pressure other then exactly straight back on the buffer can snap it. Which as you know you can't slide the bolt straight out the back so every time you remove it, you're putting pressure on the rubber buffer that can snap it. Mine didn't break the same way as the guy in the video but you get the point.
