Quick-scoping is effectively an exploit of game mechanics, allowing experienced players to land high damage and/or high accuracy shots at ranges scopes were not meant to be useful at. It is done by placing the aim outside of scoped view, zooming for just a split-second and shooting immediatelly.
Various FPSs dealt with this exploit in different ways. In Team Fortress 2 it is impossible to shoot at all for 0.5s after scoping with sniper rifle.
I didn't manage to test it yet, but I am sure high level players already know or would be interested to know if accuracy and damage bonuses to sniper weapons in HAWKEN are applied immediatelly on zoom, or only when zooming animation is over, or somewhere in between.
EDIT:
By simply observing KE-Sabot tracer I can definitelly tell that the bonus starts to apply well before zooming animation finishes, but not immediatelly. The small delay means its is not highly exploitable, but I would be surprised if experienced players weren't already taking advantage of this.
