I realize how stupid this will make me sound, but I will ask anyway. I recently disassembled my VZ-58 for cleaning and reassembled (here is the stupid part) without the striker. Before I saw the striker setting on my table, I attempt to cycle the action. That one attempt seemed to jam the action. The bolt won't quite go home, nor will it come all the way open. In adddition, the back cover with the springs attached will not come off. It can pop up a little, but something holding down. I have attached pictures. If anyone has a hint, a clue, an idea, or any thought for a stupid person, I would be very grateful indeed!

Just wondering if anyone here has any experience with building VZs from parts kits. The receivers exist, and a while back I bought one with intent to build. Main stumbling block seems to be in removing/pressing in the barrel, and no gunsmiths I talked to had the facilities to do so. While we're on the topic, has anyone put enough ammo through the VZ to shoot out the barrel?
