Friends,
I had a bull barrel and a picatinny rail installed and an action job done on a Mk II. The pistol was blued. I shot it several times with no issues. Last weekend I shot it and when I finished I put a spent casing in the chamber so I could dry fire it to release spring tension. I went to the range a day or so later and could not muscle the bolt back. I took it home and was able to get the bolt to go back with a 22 cleaning rod and a rubber mallet. I had to drive the mainspring pin out with a wooden dowel and the mallet. I now cannot get the pistol reassembled. The ms pin does not want to go in all the way. I have tried using a different ms assembly and bolt assembly and obtain the same result. I have tried slightly adjusting the frame receiver alignment but it makes no difference. Once or twice I was able to fully insert the ms pin when the bolt was not in the receiver but now I am unable to do even that. Any thoughts/suggestions/guidance would be appreciated. Thank you!
