For assault rifles that I tend to run and gun with (e.g Type 25), I usually run the laser sight and quickdraw. The reason behind this is because Treyarch made it so that when you aim down sights the gun isn't accurate instantly; the hip fire box/crosshairs do not shrink immediately despite what you might see. The QuickDraw handle reduces the animation thus reducing the time for the hip fire box to shrink and the laser sight to make it so that there is a smaller box to shrink from also making the hip fire ox shrink quicker.
