Oh, okay, thanks. Perhaps make reference to aforementioned troublemaking nature? Ah, I see. Well, my usual source says nothing of it. I say it's your call- whether the eyepiece is functional or even matters, or if you want to go with set-standard pieces, or have Nuju's Matatu be a variant of some kind and Rauta's is the "standard" scopeless. Okay, that's fine. I still think it would be useful, especially in tandem with Iron Elemental powers.
