With the recent changes to gauss barrel I am not sure if its worth it to use feint anymore. The way it works now is, when you put gauss barrel on you have to wait 15s to take it off, BUT putting it back on after you take it off has no CD. So if you need the quick mobility, such as Ravana orbs it might be better to just drop it for the orbs then slap it back on.

Feint 120*1.56 = 187.2
Split shot 140*1.2 = 168 not including autos gained.
