Hmm your recoil rod/guide has gotten stuck. Can you not rotate the barrel link (at the end of the barrel) and remove? Might help if you can do that. I seem to remember being able to do that on most models.

Only other thing I can think of is to go fishing with a small screw driver and see if you can unlatch the recoil rod/guide from whatever it's stuck on...
