So i found a riffle called "strange suspect" and in the description it says "this weapon can be fired in full auto-mode" So i did the grind hunting down space turtles and running around old Russia searching for the metal plant things after two days of doing dailies and farming supplies i finally was able to upgrade it The gun usually does a 3 round burst mode , that i have to press the trigger every time to shoot well with the upgrade i thought it would be full-auto , not 3 round burst but all it did , is it made it to where i can hold down the button but it still does 3 round burst with a small pause in-between each burst is there a button i should press to activate my full-auto mode ?
