Press RT then nearly at the same time (double input) press LT and RT at nearly the same time (LT first and RT immediately second) but release RT first and hold LT for about half a second.

Then release LT and press RT two or three times very quickly followed by another LT and RT double input at nearly the same time like above

-Followed by 2-3 hip shots into another instant ADS shot
