I don't think it's as simple as that -- Wrex has been fighting for many centuries, and I'm sure he's faced skilled snipers more than once. Given that he's still alive, he clearly knows how to handle the situation.

Personally, I'm not really inclined to speculate, but if I must, I think the most appropriate thing would be for it to be a tie -- like the time Wrex tells about when he fought that asari commando for days on end, and neither of them managed to kill the other.
