I don't even know if he has that thing still. Considering he was arrested after S6 it would've made sense for it to have been taken, but I'm not sure wether or not he got it back. At any rate we haven't seen it since Reconstruction. For all we know RT forgot about it. So I'm not putting much faith in something that hasn't been relevant for five years (hell, it wasn't even in the backstory).

And considering Wash just got shot by that same railgun and got up, it'd just feel like a cop-out if it only killed Sarge.
