Model 98 RT Trigger Kit Free yourself from batteries without sacrificing the firing rate of your paintball marker. This upgrade for your Tippmann increases your firing rate without batteries or electronics. The kit puts an air-assisted solenoid behind the trigger allowing your gun to achieve a faster firing rate. Find the trigger's "sweet spot" and achieve a full-auto effect from your otherwise semi-automatic paintball marker. As long as you have air in your tank, your paintball gun will fire. Work's great with Tippmann's air-driven Cyclone Feed System (Response Trigger Adapter kit is also required to simultaneously operate the Response Trigger and Cyclone Feed System).
