|Install your own reactive trigger assembly in your Tippmann A5! Drastically increases your rate of fire. Utilize patented technology for up to 15 balls per second air-assisted firing. By siphoning off a tiny amount of air pressure, the reactive trigger provides bounce-ability that can give you field-legal full-auto when you need it. By applying the perfect amount of pressure to the trigger, the trigger begins to bounce between the piston and the shooter's finger, sending the gun into a sort of full-auto mode.
