Well, sorry for wasting your time. I got it back together. I straightened the pin as much as I could, filed down the ends to knock off any mushrooming, tried a different method of getting the block straight and was very ginger with the pin and it went on through.
Holy shit is all I have to say about the gun. Love it. Might have to get me one.
It only has 9 successful cycles on it. Had the second 3" round FTE but did the last 4 of the 10 round box I had in rapid fire with no problems. It still needs work done to it though. It wont cycle low brass 2.75" shells fully. It might loosen up over time and fully cycle but it's not right now. It will go far enough to reset the trigger but not far enough to eject the shell.
My boss has one and he said his will cycle anything you put in it.
