Correct name of a part for a 12C 22 rifle

[ELT]

I just picked up a 12c. On the action bar there is a spring loaded button that you depress to slide the bar back far enough to remove the bolt. The head of that button is broken off. What is the correct name for that stop button so I can mabe get it from a parts source.

I have been using that websight for parts for a while, thanks. What I think the part is called is the action bar plunger, but its hard to tell for sure. Of course they are sold out of that piece too.
