 522-SD bolt problem

My wife has a 522-SD and was at the range last weekend with it. It was firing fine, until a round misfed, and the bolt closed on it almost all the way. The bolt wouldn"t pull back, and the rifle had to be disassembled to remove the round. As we didn't have the proper tools, the range master took it apart, and some small parts fell out. I think we got them all, but now I can't reassemble the bolt correctly.

The firing pin is loose, and I am not sure how it is supposed to be secured. I have a small spring and what looks like a retainer pin, but don't know how it all fits together. With the firing pin loose, the rifle will reassemble, but the bolt still can not be pulled back, so I am not sure if something else is missing, or broken.

Does anyone know of a pictorial or guide that clearly shows how the bolt/ firing pin assembly is supposed to go together? Or a picture of a properly assembled one, so I can visually compare it to mine to see if I am missing parts?

I'd like to get this rifle back together, as my wife really likes it. Plus she has commandeered my .22 AR to use in the mean time, and I'd like that back.

Greg,
It sounds like the set screw that holds in the firing pin retention pin fell out.Then the retention pin that you have fell out allowing the firing pin to unlock and get stuck. Look at the breakdown and you will see whats involved.If it is something you can fix we can hook you up with the parts..If not call 1-800-290-0065 extension 140 and darwin can set you up with a R/A number to return it.Hope this helps

After reviewing the breakdown instructions, and examining the rifle, I find I am missing the firing pin retainer pin and the set screw that holds it in place. Where would be the best place to get replacements for these parts?
