What stop pin fits my mini barrage?

[Sitcomdad83]

Looking to customize my mini barrage I've found springs now I'd like another stop pin. I've seen ones for the mini bug out and mini griptillian online. Would a bug out or mini grip pin fit?

On the mini barrage,It's not only a stop pin but a thin walled sleeve that fits over it.Good Luck with the mod.
