The funny part is, if they DID give you access to Barrage, since you only have Barrage+1, you'd still only shoot 1 ammo.
Lol, sorry another question for you, I notice there are a few Snapshot items like Zha'Go's Barbut and Aurore Beret. are they noticeable in there effect?
Just remember: Preshot - Midshot, you only need the snapshot gear on before you start your attack then can switch to your normal TP set in the middle of your shot.
