A5, X7, 98 EVT Piston Housing

Designed with performance in mind. With markers cycling faster due to electronics and other upgrades, we decided to improve some other items as well. Here is our new EVT Extreme Vent Technology housing.

  • testing confirms a net velocity increase at the chrono
  • super fast cycling using EVT, early venting which returns the piston assembly that much sooner
  • Extreme Vent Tech also offers venting in multiple stages.
  • matte finish matches your marker perfectly

NOTE: Shown on the cyclone feed system which is NOT included. This housing will fit any Tippmann marker with a Cyclone feed system installed.

* Available in Black or Silver
