Oh….Im sorry, I guess I kinda thought everyone knew what I felt silly asking! I was told that these pins are not of the tapered variety. Therefore, I was told to look carefully at both side of the block where the pins were. The side that seems to occupy most of the holes opening….should represent the side it was installed upon. His reasoning was that the pin head that was most flush…or maybe even mushroomed outward a bit is NOT the side to try to drive from. He said to place a few drops of “Kroil” to the side that you’ll drive from….and let it stand for an hour in a good normal room temperature to allow it to seep into and around the pin. I did that, and after an hour used a smaller dia. Punch than the OD of the pin. Both came out fairly quickly without deformation. Now, my big question is how to drive the Gas Block forward a bit to allow the tube to be removed? I think I’ll try the same technique with the Kroil oil and gently tap it fwd.
