Okay I'm kinda in a pickle! I just finished putting a barrel on my latest model 116 project. I took the firing pin and put the bolt handle back on to set the headspace. Then when I go to put the firing pin back in I notice that I can't get the retaining bolt to thread back in the back. It looks like the firing pin has become uncocked somehow when it was taken apart. I've never had this happen before when I've removed the firing pins. The little sleeve that goes over the back of the firing pin won't go down all the way so that the retaining bolt can catch the threads. How do I get it cocked so that I can get the retaining bolt to go back in? It looks like something got out of alignment because it took some work to get the slots to line up on the sleeve and firing pin (if that makes sense). What do I do? Thanks in advance for any advice.
