A reverse plunger is a type of plunger mechanism that many N-Strike blasters use. This is considered to be less powerful than the direct plunger mechanism because it reduces range and sometimes accuracy of the blasters. The most recent Nerf blaster to have a reverse plunger is the DartFire.
A reverse plunger's main parts are the catch, spring, plunger tube, the O-ring, and a fixed plunger rod. The plunger rod does not move with the plunger itself, and is fixed in place, it is only used for pushing air out. When primed, the plunger tube moves back, and is locked on to the catch. When it moves forward after the firing trigger is pressed, it pushes air into the plunger rod.
The reverse plunger mechanism works in a much more complicated way than the direct plunger. In a clip system reverse plunger mechanism, the plunger tube not only moves backwards, but also forward while simultaneously grabbing a dart from a clip, drum, magazine, or integrated ammunition holder.
This plunger system has reduced range due to mechanical inefficiencies of the design. When the plunger moves back it creates a seal, but when the plunger moves forward, the seal breaks and some of the air leaks out. A reverse plunger also typically leaves a void between the plunger and the dart chamber. The air inside this void acts as a spring, pushing back against the air entering from the plunger, greatly reducing the force delivered to the dart. The result is a much less efficient air delivery system, which is why reverse plungers are disliked by many Nerfers.
