Mossberg 500 shockwave part.

I was cleaning my shockwave today and this tiny little piece fell out of the receiver. Its flat on one side and round on the other. Maybe 1/4" long at most. Anybody have an idea what it belongs to?

Was it accompanied by a spring? Looks like a pin that is usually pushed by a spring to hold something in place. A locking pin of some sort. What is not staying where it should?

This part is the only thing that fell out. But you're rightit does look like a detent of some sort. Everything "seems" to still function as it should...

Could that be a guide for the receiver? The round end rides in a groove. I cant read the schematic clearly.

Its got to be that elevator stud. 500s don't have anything that looks like that pin. Should see a hole on one side or the other on the receiver. Might be able to stake it back in.
