started building my son's ar-10 tonight. We began putting the bolt catch in place but he was having trouble getting the threads started on the pin. So, I removed the catch and put the pin in by itself. It threaded most of the way and then the edge of the allen head broke off. I have tried a pair of needle nose pliers to back the pin out with no luck. Any ideas? Thanks.
