No idea on if Hot Swap affects aim assist. Anyway, it seems aim assist levels are higher the faster the fire rate goes. Raid sniper and iron banner sniper are more of an aimbot than 1kYS.I've got one with Hot Swap but haven't actually leveled it - is hot swap related to aim assist in any way? Snipers are already perfectly 'accurate' but I don't know what they mean by 'accuracy' in terms of that perk.
I did notice the very short range scope and that had me interested. It also sounds cool, which is why I use Hereafter.
