SFAR Magazine Catch/Release Assembly Compatibility

Does anyone know if the magazine catch and release assembly has any commonality with the AR-15 platform? It looks like the button and spring is likely compatible, but the catch assembly (the threaded stud part in particular) has to be longer, as in the AR-10. Can anyone confirm if an existing AR-10 catch will work?

I do not "know" because I do not have a SFAR. I know AR-10 and SR25 mags work in it, so it would make sense EXCEPT I know the bolt is different, but that the charge handle is not..... I am not helping here at all. Maybe call Ruger CS and ask?
