An easy way to tame/knockout a giga is to, craft 4 metal dinosaur gateways with a large bear trap. You place 3 of the gateways in a square shape spread a few inches from each other. Then place the large bear trap in the middle. Then with an argy or ptera pick up a dodo and lure the giga into the center of the gates to get trapped by the trap then jump off and place the last Dino gate in the open area and the giga will be trapped and able to shoot and tamed:)
