The Vector is actually a pretty divisive gun. Either you’re going to love it or hate it, and shooting it is a big part of that equation. There’s no doubting they’ve thoroughly reinvented the carbine/SMG with this design, though.
This is probably the best review I’ve seen about this gun (or rather, family of guns) and it gets into details that are even new to me, and I’ve had multiple range sessions with these gun (including fun-button Vectors).
Another good show by sootch00. Head over to his YouTube channel for more.
