I will say in the most recent OB update, George is now much better at shooting targets with the gun. In MP before, he was 0% effective at pulling the trigger. Now it seems like he is 100% effective at firing the gun in the right direction (based on a few servers I've tried.)
He does not seem to lase the target for long enough to get a laser range for the gun, so all the shots still miss at all ranges and all speeds.
