    The key to installing them is to keep them straight.

      The proper method is to measure across the end gap at the end of the coil so you are getting the SMALLEST possible outside diameter of the pin.



      There are a lot of bad parts kits floating around with oversized (metric instead of inch) bolt catch pins.
      When you run into these, the only fix is to throw away the crappy pin and get a proper one.
      Yea once I sanded down just enough to get it started.... it went in just fine. No squishing or pounding. I knew if I could get it started it would be fine. Works like a charm.

          Easy fix?

          Brownells roll pin holder punch set. Makes starting roll pins mindless.

          Then a standard roll pin punch set to finish.

                That was my first thought, and then the number drills to determine the diameter of the hole. Once I know it's the right dimensions, then bevel one end to ease starting it.
