  1. is there a trick, I am missing, to reinstall the firing pin retaining pin. because I always see you guys put yours in and it goes right in, and it seems like I always have to fight with mine to get it reinstalled. what the deal

  2. I have heard people say run an AR15 "Wet" but never knew if that meant soak the entire BCG in oil or just the gas rings but after watching this video I will just lube my BCGs that same as in this video
