It took a long time imagining it, but then I’m out of ideas why it’s not monolithic. Having two eyesights and running with a weird angled gun aren’t as a problem as servicing that thing and rely on it. But just like OP I would’ve seen a vif of how and why it’s that way.
Looks rather simple, the gun itself doesn’t change shape, only the cover. Looks like there’s a small periscope for aiming.
