Cleaning the ar10 and the firing pin and firing pin retaining pin came out. The retaining pin has a tensioning split toward the end, but slides in and out easily. Should I 1 - try to slightly spread the tip or 2 - install and tap with punch to spread? Don't have a spare laying around and have hogs to kill. Not asking for a friend. Thanks!
It is a pin, not a carter key.
