Coming with the 6th generation of Spring Thunder blasters, the plunger head was changed from a turned nylon catch to a composite 3D print and steel assembly. With the primary upgrades being the wear surface upgrade from machined Nylon to a solid steel washer, this greatly improves the hardness of the catching surfaces for longer lasting more reliable firing action.
The extension of the 3D printed plunger head also helps to improve the sizing tolerances of the part, making for a more consistent build.
This is being added to the shop by request for anyone who wishes to upgrade their model 1-5 blasters with one of these new plunger heads. All Spring thunders should be compatible with this upgrade.
