To cock the rifle, press cocking knob located under the reservoir till you hear a click as the trigger engages. The Techstar has been designed so that it can be cocked easily at the moment you choose to shoot with a minimum of movement that might alert your quarry.

Should you require to de-cock your rifle, push the cocking knob in and hold firmly, pull trigger and slowly release knob until it is back in the rest position.
