Plunger

A plunger is a component of the internals of a blaster. It is the part that takes in the dart and pushes it into the barrel to launch it. The size and shape of a plunger varies depending on the blaster; there are only two mechanisms that plungers are incorporated into. Some blasters, like the Rough Cut 2x4 use two plungers rather than one, however, these two plungers are meant for making multi-fire easier and have more distance.

Many modders often pad plungers or replace plungers to make them last longer or perform better.

Direct plunger
Direct plunger systems are most powerful plunger type. It consists of the plunger tube directly launching the dart out of the barrel, usually by pushing it with enough force. Many single shot blasters use this mechanism, such as the Nite Finder EX-3; it was more commonly used with the introduction of the N-Strike Elite series in 2012.

Reverse plunger
Reverse plunger system were the most common mechanism for most pre N-Strike Elite blasters. The reason it is called a "reverse" plunger is because the plunger tube moves backward to grab the dart and then launches it through the barrel. Examples of reverse plunger blasters include the Recon CS-6, LongStrike CS-6, Centurion, and the Maverick REV-6.
