Anyone have any idea what would keep one of these from firing ? Seems like it was having light primer strikes, then quit all together. Belongs to a guy I work with, so I didnt get to see it shooting, or get to witness what it was doing. It's terribly dirty, I think maybe the firing pin channel is gummed up.

Any ideas ?

If it had decreasing light primer strikes, either the firing pin chamber is very dirty, or the firing pin spring is worn.  Both are very easy fixes

I took it apart last night. It was extremely dirty, one of the nastiest guns I've ever seen actually. Took a lot of solvent and brushing to get it clean. Now it will launch a ink pen out everytime you pull the trigger. Before it wasn't even shaking it. So I'll try it later and see.

By the way, that piece that goes at the back and holds the springs has came apart. I assume thats part of thr problem.

Where can you find parts ?

Well I did get it firing every time you put a round in the chamber. Now the problem is it will fire only once. The next round will be between the barrel and the bolt, with the lead pointing straight up. If you put a round in the chamber and cycle it by hand, the extractor isn tpulling the round back out. Is it suppose too ? I dont know anything about these guns, just trying to help him get it fixed.
