You need the Fleetflammer to make this possible. Kinsect Charge time– lets you charge your kinsect in no seconds. Yesterday I got 3 K.O.'s off on Teostra in a duration of 3 min. Hold R+X→wait until charged→shoot→hold R+X permanently→send back with R+A→shot is already charged in not even 1 second→shoot again. And go on like that. Meanwhile you should spam mounts, so you can aim the head easier.
